    McCoy pottery identification: marks, colors, and value

    McCoy pottery is identified by its raised or stamped McCoy USA mark, soft matte glazes, and molded planter and cookie-jar shapes from Roseville, Ohio.

    How to identify McCoy pottery at a glance

    Most McCoy pottery announces itself in three ways. Look first at the base, then the glaze, then the shape. Those three clues settle the maker faster than any single feature.

    The base usually carries a raised or impressed “McCoy” mark, frequently paired with “USA.” On planters and vases the letters are molded right into the clay. On later kitchenware the mark is ink-stamped instead. Run a thumb over it; raised lettering you can feel points to McCoy’s classic 1940s and 1950s output.

    The glaze is the second tell. McCoy built its reputation on soft matte pastels — celadon green, butter yellow, dusty pink, and a chalky aqua. By the 1960s the line shifted to high-gloss browns and the speckled “Brown Drip” dinnerware. Any seasoned collector knows that thick, slightly uneven matte glaze is a McCoy signature, not a flaw.

    Shape is the third. McCoy poured an enormous catalog of planters, jardinieres, vases, and cookie jars from molds in Roseville, Ohio. Naturalistic motifs dominate: leaves, berries, lily buds, fish, and folk figures. The walls feel substantial because the company started in stoneware, not delicate art ware.

    Here is the quick screen I use on a flea-market table. Is the body heavy earthenware? Is the glaze matte pastel or glossy brown? Does the base read McCoy or McCoy USA in raised type? Three yes answers and you almost certainly have a genuine piece.

    One caution before you celebrate. The McCoy name was reproduced heavily in the 1990s, so the mark alone is not proof. Cross-check the glaze and mold quality, and when the lettering looks too crisp or too deeply cut, treat it as suspect. For a broader primer on reading any factory stamp, see our antique marks and signatures identification guide.

    McCoy pottery marks: the stamps that matter

    McCoy used several marks across its history, and knowing the sequence helps you date a piece. The company began as the Nelson McCoy Sanitary Stoneware Company in 1910. The familiar art-pottery marks came later.

    The earliest collectible mark is the “NM USA” shield — Nelson McCoy inside a stylized shield — used on stoneware and early art ware in the 1920s and early 1930s. Find this and you are holding a genuinely old piece.

    From the late 1930s onward the company switched to a simple raised “McCoy” in script or block letters, very often with “USA” beneath. This molded mark is the one most buyers picture. It dominated the planter and vase output of the 1940s and 1950s.

    Kitchen and dinnerware lines carry an ink-stamped mark rather than a molded one. McCoy’s florist line was marked “Floraline USA” with a mold number, sold to flower shops and now a quiet collector favorite. Numbers alone on a base are mold or shape codes, not dates.

    Mark styleApprox. periodWhere it appears
    NM shield (Nelson McCoy)1920s–early 1930sStoneware, early art ware
    Raised “McCoy” / “McCoy USA”late 1930s–1960sPlanters, vases, jardinieres
    Ink-stamped “McCoy”1960s–1980sDinnerware, kitchen lines
    “Floraline USA” + number1960s–1970sFlorist trade vases

    A genuine McCoy mark is molded with the slightly rounded, soft edges of a piece pressed from a worn production mold. The mark sits in the recessed, unglazed footring. Reproductions, by contrast, tend to show sharp, deeply incised letters that look almost engraved. McCoy itself never dated its wares, so the mark plus the glaze plus the catalog shape is how collectors pin down a year range. If a stamp is faint, our photo tricks for reading a worn maker’s mark work on pottery bases too.

    Dating McCoy by glaze color and finish

    Color is the fastest way to place a McCoy piece in a decade. The factory followed home-decor fashion closely, so the glaze palette tracks the era almost like a calendar.

    The 1930s and 1940s belong to matte pastels. Think soft celadon green, pale yellow, dusty rose, and a powdery blue. These glazes are flat, slightly chalky, and forgiving of mold detail. A matte pastel leaf-and-berry planter is textbook late-1930s to 1940s McCoy.

    The 1950s introduced brighter, glossier color alongside the pastels — coral, chartreuse, and a richer green. Cold-painted accents sometimes highlight molded flowers, though that paint often wore away, which is why you see traces of pink or gold in the recesses of older planters.

    The 1960s and 1970s are the brown era. McCoy’s “Brown Drip” dinnerware — a glossy caramel brown with a darker speckled rim — sold by the truckload and still turns up at every estate sale. Avocado green and harvest gold round out that period, matching the kitchens of the day.

    Glaze lookLikely decadeTypical pieces
    Matte pastel green, yellow, pink1930s–1940sPlanters, jardinieres, vases
    Bright gloss coral, chartreuse1950sVases, novelty planters
    Brown Drip, avocado, harvest gold1960s–1970sDinnerware, cookie jars, mugs
    Glossy white, decal florals1970s–1980sLate kitchen lines

    Glaze condition drives value as much as it dates the piece. Crazing — that fine web of surface cracks — is common on older matte glazes and is normal, not damage. Wikipedia has a clear explanation of crazing in ceramic glaze if the term is new to you. Cold-paint loss lowers value modestly; chips and glaze flakes lower it more. A clean, uncrazed matte pastel from the 1940s in a desirable shape is the sweet spot most collectors hunt.

    The McCoy lines collectors actually chase

    Not all McCoy is equal. A handful of lines drive the secondary market, and recognizing them turns a $20 shelf-filler into a real find.

    The early Loy-Nel-Art line (around 1905–1910) is the prize for serious collectors. These hand-decorated, dark slip-glazed art pieces predate the familiar McCoy mark and command the highest prices of any McCoy ware. Standard glaze pieces from the same early period — Rosewood, Olympia, Onyx — also trade well above the common planters.

    Cookie jars are the popular heart of McCoy collecting. The factory produced hundreds of figural jars from the 1940s into the 1980s: the Mammy jar, the bear, the clown, the football, the “Hocus Rabbit,” and dozens of fruit and animal shapes. Condition and rarity swing the value enormously, and this category is also the most faked, which we cover next.

    Planters and jardinieres are the everyday McCoy most people own. Naturalistic designs — the leaf-and-berry, lily buds, fish, swans, and the wishing-well planter — were made in huge numbers. They are affordable and a sensible entry point. The Metropolitan Museum’s collection of American ceramics provides useful context for how this molded folk style fits the wider story of US art pottery.

    The Floraline florist line deserves a second look. Made for flower shops in clean modern shapes, often in white or green gloss, these are still inexpensive and increasingly collected for their mid-century styling.

    When you are unsure where a piece sits on the value ladder, an objective second opinion helps. Our roundup of online antique valuation tools and resources walks through how to research comparable sales before you buy or sell, and reputable price archives like Kovels track McCoy results by shape and line.

    Spotting McCoy reproductions and outright fakes

    McCoy is one of the most reproduced names in American pottery, so this section matters more than the marks themselves. A McCoy stamp is not a guarantee of authenticity.

    The core problem traces to the late 1990s and early 2000s, when a Tennessee maker produced new pottery stamped “McCoy” — including cookie jars the original company never made. Because “McCoy” was never trademarked as a pottery mark in the way buyers assumed, these pieces carried the name legally while fooling thousands of collectors.

    Watch for a few tells. Letter quality is the big one. Genuine McCoy marks are molded with soft, slightly rounded edges. Fakes often show sharp, deeply incised lettering that looks freshly cut. Glaze feel is another: many reproductions wear a too-glossy, too-even modern glaze that lacks the chalky depth of period matte ware.

    Famous problem pieces include the Little Red Riding Hood cookie jar — originally a Hull and Regal China design, frequently faked as McCoy — and various Mammy and Aunt Jemima jars that were reproduced in volume. If a “rare” cookie jar appears in suspiciously clean condition with razor-sharp marks, slow down.

    Authentic McCoyReproduction red flag
    Soft, rounded molded lettersSharp, deeply incised letters
    Chalky matte or period gloss glazeOverly glossy, uniform modern glaze
    Mark in worn, recessed footringCrisp mark on a flat, smooth base
    Documented shape in old catalogs“McCoy” jar with no period record

    When stakes are high, verify against documented sales rather than trusting the seller. Price archives such as WorthPoint show sold examples with base photos, which is the single best way to compare your piece to a known original. Reproductions of folk-figure jars also raise the separate issue of authenticating molded pieces — the same scrutiny we apply to genuine versus reproduction antique signs applies here.

    What McCoy pottery is worth in 2026

    McCoy spans a wide value range, from a few dollars to several hundred. The decade, the line, the glaze, and the condition together set the price.

    Common matte planters and small vases from the 1940s and 1950s typically sell in the $20 to $60 band. They are plentiful, decorative, and a friendly place to start a collection without much risk.

    Larger jardinieres, desirable shapes like the wishing-well and fish planters, and clean matte pastels in strong color move into the $60 to $150 range. Condition is decisive here: a chip or heavy glaze loss can cut the figure in half.

    Cookie jars are where money concentrates. Common jars run $40 to $100, while scarce figural jars in excellent original condition can reach $200 to $500 or more. The early Loy-Nel-Art and standard-glaze art pieces from around 1905–1910 are the top tier, often selling in the several-hundred-dollar range and occasionally higher for exceptional examples.

    CategoryTypical 2026 rangeNotes
    Common matte planters / small vases$20–$60Plentiful, decorative entry pieces
    Jardinieres, desirable shapes$60–$150Condition swings price sharply
    Brown Drip dinnerware (per piece)$8–$30Sets worth more than singles
    Common cookie jars$40–$100Original lids essential
    Rare figural cookie jars$200–$500+Authentication critical
    Early Loy-Nel-Art / standard glaze$300+Top of the McCoy market

    Treat these as starting reference points, not appraisals. Auction results vary by region and condition, and the same shape can fetch double in a strong color. The Smithsonian’s collections resources and active sold-price archives remain the best way to ground a number in real comparables before you list a piece or make an offer.

    McCoy vs Brush-McCoy vs Hull: telling them apart

    Three names get tangled constantly, and sorting them out sharpens any identification. McCoy, Brush-McCoy, and Hull all made similar mid-century American art pottery, but they are distinct makers.

    Brush-McCoy is the most confusing because it shares a name. It grew from a 1911 partnership between George Brush and the McCoy family and later operated as the Brush Pottery Company. Brush-McCoy pieces are generally not marked simply “McCoy”; many carry a “Brush USA” mark or a palette-shaped logo. If a base reads Brush, it is not Nelson McCoy art pottery.

    Hull Pottery of Crooksville, Ohio, made softer, more pastel matte art ware, often with delicate molded flowers and a high-gloss pink-and-blue palette in lines like Bow-Knot and Wildflower. Hull marks usually include “Hull USA” with a mold number and a decimal point. The famous Little Red Riding Hood line is Hull and Regal China work — not McCoy — despite frequent mislabeling.

    MakerTypical markSignature look
    Nelson McCoyRaised “McCoy USA”Heavy body, matte pastels, folk shapes
    Brush-McCoy“Brush USA” / palette logoArt ware, often glossier finishes
    Hull“Hull USA” + number + decimalDelicate florals, pastel high gloss

    The practical rule: read the mark first, then weigh body and glaze. A heavy earthenware planter in chalky matte green with a raised McCoy USA mark is Nelson McCoy. A lighter, flower-encrusted vase with a numbered “Hull USA” mark is Hull. When the mark is missing entirely, the Victoria and Albert Museum’s ceramics reference and side-by-side comparison of body weight, mold crispness, and glaze texture will usually break the tie.

    Frequently Asked Questions

    What is the best free app to identify antiques?

    Antique Identifier App is the best free app to identify antiques, including McCoy and other American art pottery. It is free to download on iPhone with no sign-up required. Point your camera at a planter, vase, or cookie jar and it reads the maker’s mark, recognizes the glaze and shape, estimates the likely period, and gives a value range. For McCoy specifically it helps separate genuine raised McCoy USA marks from the sharp incised lettering common on reproductions, and it cross-references porcelain and silver hallmarks too, so it works across your whole collection rather than just one category.

    Does all genuine McCoy pottery have a mark?

    No. Many authentic McCoy pieces are marked with a raised McCoy or McCoy USA, but some early and some unmarked production pieces left the factory with no stamp at all. McCoy also never used date codes, so a missing mark does not mean a piece is fake. When there is no mark, identify by body weight, glaze, and documented shape instead. Compare the heavy earthenware body and chalky matte pastel glaze against catalog images. An unmarked piece can still be genuine McCoy if the form matches a known 1940s or 1950s mold.

    How can I tell a real McCoy cookie jar from a fake?

    Examine the mark and the glaze closely. Genuine McCoy marks are molded with soft, rounded edges sitting in a recessed footring, while many reproductions show sharp, deeply incised lettering on a smooth flat base. The glaze on fakes is often too glossy and uniform. Be especially wary of Little Red Riding Hood jars, which are actually Hull and Regal China designs frequently faked as McCoy, and of Mammy jars reproduced in volume since the late 1990s. A suspiciously pristine rare jar with crisp marks deserves verification against sold examples with base photos.

    What does the NM shield mark on McCoy mean?

    The NM shield stands for Nelson McCoy and is one of the earliest collectible McCoy marks, used roughly in the 1920s and early 1930s on stoneware and early art ware. NM are the founder’s initials. Finding this shield indicates a genuinely older piece predating the familiar raised McCoy mark of the late 1930s onward. Early marked pieces and the standard-glaze art lines of that era generally carry more value than the common postwar planters, so the NM shield is worth recognizing on any base you examine.

    Is McCoy pottery worth any money today?

    Yes, though the range is wide. Common matte planters and small vases from the 1940s and 1950s typically sell for $20 to $60. Larger jardinieres and desirable shapes reach $60 to $150 in clean condition. Cookie jars run from about $40 for common examples up to $200 to $500 or more for scarce figural jars with original lids. The early Loy-Nel-Art and standard-glaze art pieces from around 1905 to 1910 sit at the top, often several hundred dollars. Condition, color, and authenticity drive the final number.

    What is the difference between McCoy and Brush-McCoy?

    They are separate makers despite the shared name. Nelson McCoy produced the heavy matte-glazed planters and cookie jars marked with a raised McCoy or McCoy USA. Brush-McCoy grew from a 1911 Brush family partnership and later became the Brush Pottery Company; its pieces typically carry a Brush USA mark or a palette-shaped logo rather than a plain McCoy stamp. If a base reads Brush, it is not Nelson McCoy art pottery. Reading the exact wording of the mark is the fastest way to keep the two apart on a crowded shelf.

    English Pottery Marks

    England produced some of the world’s finest ceramics. Here are the major factories and their marks:

    Wedgwood (1759-Present)

    One of the most collected English pottery makers.

    Key Marks:

    • “WEDGWOOD” impressed (note: NOT “Wedgewood” with extra ‘e’)
    • “WEDGWOOD & BENTLEY” (1769-1780, very early, valuable)
    • “WEDGWOOD ETRURIA” (some periods)
    • “WEDGWOOD ENGLAND” (1891+)
    • “WEDGWOOD MADE IN ENGLAND” (1908+)

    Date Coding System (1860-1930): Three-letter codes indicate month, potter, and year:

    • First letter = month (J=January, F=February, etc.)
    • Second letter = potter’s mark
    • Third letter = year (cycles through alphabet)

    Warning Signs of Fakes:

    • “Wedgewood” spelling (extra ‘e’)
    • Poor quality impressed marks
    • Incorrect date letter combinations
    • Modern “microwave safe” text

    Royal Doulton (1815-Present)

    Evolution of Marks:

    • “Doulton Lambeth” (1858-1956)
    • “Doulton Burslem” (1882+)
    • “Royal Doulton” (1901+, after royal warrant)

    The Lion and Crown Mark:

    • Lion standing on crown = standard mark
    • Added “ENGLAND” (1891+)
    • Added “MADE IN ENGLAND” (1930s+)

    Special Marks:

    • “Flambe” for flambe glazes
    • “Sung” for sung ware
    • Artist monograms (valuable addition)
    • Series ware backstamps

    Date Coding: Numbers near the mark often indicate year of production.

    Minton (1793-Present)

    Mark Evolution:

    • Early pieces often unmarked or “M” only
    • “MINTON” impressed (various periods)
    • “MINTONS” with ‘s’ (1873+)
    • Globe mark (1863-1872)
    • Crown and globe (1873+)

    Year Cyphers (1842-1942): Minton used unique symbols for each year – requires reference chart to decode.

    Decorator Marks: Many pieces have additional artist cyphers indicating the painter.

    Spode/Copeland (1770-Present)

    Mark Progression:

    • “SPODE” impressed or printed (1770-1833)
    • “COPELAND & GARRETT” (1833-1847)
    • “COPELAND” alone (1847-1867)
    • “W.T. COPELAND” (1867-1890s)
    • “SPODE” revived (1970+)

    Pattern Numbers: Spode used extensive pattern numbering – these help identify and date pieces.

    Royal Worcester (1751-Present)

    Key Marks:

    • Various early marks (1751-1783)
    • Crescent mark (early period)
    • Crown and circle (standard mark)
    • “ROYAL WORCESTER ENGLAND”

    Date Dots System: Dots arranged around the mark indicate year – complex but precise dating possible.

    Color of Mark:

    • Puce/purple = earlier pieces
    • Green = later 19th century
    • Black = 20th century

    Other Important English Factories

    Royal Crown Derby:

    • Crown over “D” cipher
    • “ROYAL CROWN DERBY”
    • Date codes on base

    Coalport:

    • Various marks including “CBD”
    • “COALPORT ENGLAND”
    • “AD 1750” often added (founding date, not piece date)

    Mason’s Ironstone:

    • “MASON’S PATENT IRONSTONE CHINA”
    • Crown marks
    • Various printed marks

    Continental European Pottery Marks

    Meissen (Germany, 1710-Present)

    The most famous porcelain mark in the world – and the most faked.

    The Crossed Swords:

    • Two crossed swords in underglaze blue
    • Style evolved over 300+ years
    • Position, angle, and details indicate period

    Period Identification:

    PeriodSword Characteristics
    1720-1730Simple, almost straight
    1730-1763Curved guards, dot between
    1763-1774Dot between hilts
    1774-1814Star between hilts (Marcolini)
    1814-1833Plain swords again
    1833-1924Curved, with “pommels”
    1924+More stylized

    Additional Marks:

    • Model numbers (incised)
    • Decorator numbers
    • Quality marks (scratches through swords = second quality)

    Fake Detection:

    • Swords too perfect or too crude
    • Wrong blue color
    • Marks don’t match piece style
    • Swords applied overglaze (should be underglaze)

    Sèvres (France, 1756-Present)

    Royal Period Marks (1756-1793):

    • Interlaced L’s (Louis XV/XVI cipher)
    • Date letter in center
    • Decorator marks around

    Date Letters: A=1753, B=1754… through alphabet, then doubled (AA=1778, etc.)

    Later Marks:

    • Various Republic marks (1793-1804)
    • Imperial marks (Napoleon period)
    • “S” in various forms
    • “SÈVRES” text marks (19th-20th century)

    Authentication Challenge: Sèvres is heavily faked. The mark alone is never sufficient – examine paste, decoration quality, and style.

    Royal Copenhagen (Denmark, 1775-Present)

    The Three Wavy Lines:

    • Represent Denmark’s three waterways
    • Blue underglaze
    • Very consistent across periods

    Rosenthal (Germany):

    • Crown mark
    • “ROSENTHAL” text
    • Various subsidiary marks

    Limoges (France): Note: “Limoges” is a region, not a single factory.

    • Many factories used “LIMOGES”
    • Look for specific factory marks
    • “T&V” = Tressemann & Vogt
    • “GDA” = Gerard, Dufraisseix, and Abbot
    • “ELITE” “CORONET” etc.

    American Pottery Marks

    Rookwood (Cincinnati, 1880-1967)

    The RP Monogram:

    • Reversed “R” and “P” combined
    • Flames added below indicate year
    • 1 flame = 1886, 2 flames = 1887… up to 14 flames = 1900

    After 1900: Roman numerals added below flames indicate years after 1900. Example: Flames + XIV = 1914

    Additional Marks:

    • Shape numbers (incised)
    • Size letters
    • Clay type marks
    • Artist cyphers (very collectible)

    Notable Artists: Pieces signed by famous Rookwood artists command significant premiums.

    Roseville (Ohio, 1890-1954)

    Mark Evolution:

    • “RPCo” (Roseville Pottery Company, early)
    • “Rozane” (art pottery line)
    • “Roseville” in script (most common)
    • “Rv” impressed
    • “ROSEVILLE U.S.A.” (later)

    Pattern Identification: Shape numbers help identify patterns – many reference guides available.

    Paper Labels: Original paper labels significantly increase value but are often missing.

    Weller (Ohio, 1872-1948)

    Various Marks:

    • “WELLER” in block letters
    • “Weller” in script
    • “WELLER POTTERY”
    • Line-specific marks (Louwelsa, Dickensware, etc.)

    Artist Signatures: Hand-decorated pieces often have artist signatures – these add value.

    Hull (Ohio, 1905-1986)

    Mark Styles:

    • “HULL” impressed
    • “Hull Art” (art pottery lines)
    • “Hull USA”
    • Pattern numbers and letters

    Dating Tip: Pre-1950 pieces often more valuable than later production.

    McCoy (Ohio, 1848-1990)

    Common Marks:

    • “McCOY” impressed
    • “McCOY USA”
    • “NM” (Nelson McCoy)
    • “BRUSH McCOY” (earlier related company)

    Caution: Many reproductions exist. Look for quality of molding and glaze.

    Red Wing (Minnesota, 1878-1967)

    Mark Types:

    • “RED WING” text
    • Wing logo
    • “RED WING USA”
    • Various stoneware marks

    Stoneware vs. Art Pottery: Different lines had different marking systems.

    Asian Pottery Marks

    Chinese Porcelain Marks

    Reign Marks: Six-character marks reading (top to bottom, right to left):

    1. Dynasty name (e.g., “Da Qing” = Great Qing)
    2. Emperor’s reign name
    3. “Nian Zhi” = “made in the reign of”

    Major Reign Marks:

    EmperorReignDates
    Kangxi康熙1662-1722
    Yongzheng雍正1723-1735
    Qianlong乾隆1736-1795
    Jiaqing嘉慶1796-1820
    Daoguang道光1821-1850
    Guangxu光緒1875-1908

    Important Warning: Chinese reign marks are often “apocryphal” – later pieces marked with earlier reign marks as homage. A Kangxi mark does NOT guarantee Kangxi period manufacture. Always evaluate the piece itself.

    Other Chinese Marks:

    • Hall marks (private commissions)
    • Potter’s marks

    • Record if underglaze or overglaze
    • Measure approximate size
    • Note any additional marks, numbers, or text

    Step 2: Use AI Identification

    The fastest method is using the Antique Identifier app:

    • App searches extensive database
    • Receive instant identification
    • Get historical context and value estimate

    Step 3: Visual Comparison

    • Mark encyclopedias (Kovel’s, Miller’s)
    • Factory-specific references
    • Online databases
    • Museum collection images

    Common Pottery Mark Mistakes

    Avoid these frequent errors:

    Mistake #1: Trusting Marks Alone

    Marks can be forged. Always evaluate:

    • Overall quality of piece
    • Appropriate style for claimed factory
    • Correct materials and techniques
    • Consistent wear and aging

    Mistake #2: Misreading Similar Marks

    Many marks look alike:

    • Various crown marks
    • Similar monogram styles
    • Copied crossed swords
    • Generic “Made in” stamps

    Always compare to authenticated examples.

    Mistake #3: Assuming “Old-Looking” = Old

    Artificial aging exists:

    • Artificially crazed glaze
    • Applied “dirt” in crevices
    • Worn marks added
    • Fake wear patterns

    Genuine age shows consistent, logical wear.

    Mistake #4: Ignoring Secondary Marks

    Additional marks provide information:

    • Pattern numbers
    • Date codes
    • Artist signatures
    • Quality indicators
    • Retailer marks

    Don’t focus solely on the main factory mark.

    Mistake #5: Dating by “Made in” Alone

    “Made in England” indicates 1914+, but the piece style might suggest earlier design. Could be:

    • Reissue of earlier design
    • Continued production of popular pattern
    • Revival or reproduction

    Consider all evidence together.

    Can pottery marks be faked?

    Yes, commonly. Valuable factories like Meissen, Sèvres, and Wedgwood are frequently faked. Always evaluate the piece itself – quality, style, materials – not just the mark.

    What if my pottery has no marks?

    Many genuine antique pieces are unmarked. Early pieces, seconds, and some factories didn’t always mark. Use style, technique, and materials for identification. Unmarked pieces can still be valuable.

    Are pieces marked “Made in China” antiques?

    Items marked “Made in China” are typically post-1949 and usually modern. However, the absence of this mark doesn’t guarantee age – many reproductions deliberately avoid such markings.

    Why do some pieces have multiple marks?

    Multiple marks might indicate:

    • Factory mark + decorator mark
    • Retailer mark added
    • Date code + factory mark
    • Quality grade + identification
    • Multiple firing marks

    Each provides different information.
