Weller pottery marks and value guide: how to date and price your piece

The mark on the base identifies Weller pottery: impressed WELLER, incised script, or the Since 1872 stamp each point to an era between 1895 and 1948.

From a Fultonham shed to the largest art pottery in America

Samuel A. Weller started his pottery in 1872 in a small shed in Fultonham, Ohio. He hand-threw flower pots, crocks, and jardinieres, then sold them from a wagon. Collectors should remember that date. The late “Since 1872” mark refers to this founding, not to the start of art pottery production, which began more than twenty years later.

Weller moved the business to Zanesville, Ohio in 1888 and expanded into a larger plant on Pierce Street around 1890. Zanesville sat on deep clay beds and cheap natural gas, and it became the capital of American art pottery. His two closest rivals, Roseville and J. B. Owens, operated within a few miles of his kilns. The three firms poached each other’s designers for decades, which is why their early brown-glaze wares look so similar.

The turning point came at the 1893 Chicago World’s Fair. Weller saw Lonhuda ware, William A. Long’s line of hand-painted slip decoration under a glossy brown glaze. He bought into the Lonhuda Pottery in 1894 and brought Long to Zanesville. By 1896 Weller had renamed the glaze Louwelsa, a construction built from LOUise (his daughter), WELler, and SAmuel. Long left within a year, but the glaze formula stayed.

Louwelsa sold in enormous numbers. By 1905 the company advertised itself as the largest art pottery in the world, with over 500 workers and dozens of active lines. Museum collections back up the reputation. The Smithsonian Institution holds Weller examples among its American ceramics, and period trade catalogs list thousands of Louwelsa shape and size combinations.

After World War I, hand decoration became too expensive to sustain. Weller shifted toward molded commercial lines through the 1920s, and the Depression ended the remaining hand-painted art ware. Sam Weller died in 1925. His nephews ran the firm until 1948, when production stopped and the Essex Wire Company bought the plant.

For identification purposes, that 76-year run splits into three eras. Hand-decorated art ware from 1895 to 1918 carries the strongest values. Middle-period lines from 1918 to 1935 offer the best price-to-beauty ratio on the market. Late production from 1935 to 1948 is common, and prices stay modest. Every dating tool in this guide exists to place your piece into one of those three windows.

Weller marks by era: date the base before anything else

Turn the piece over first. Weller changed its marking system several times, and the base mark alone dates most pieces within a decade. Any seasoned collector checks the mark before the glaze, because Weller kept popular glazes in production for twenty years or more.

The earliest art ware carries die-impressed block letters reading WELLER, sometimes with the line name added. Louwelsa pieces often carry a circular impressed seal reading LOUWELSA WELLER with a shape number below it. Sicardo breaks the rule: most Sicardo pieces are signed on the side in script, and the base is often bare.

Here is the timeline I use at shows:

Mark	How it was applied	Era	What it signals
WELLER in block letters	Die-impressed	1895-1918	Early art ware, strongest values
LOUWELSA WELLER circular seal	Impressed stamp	1896-1924	Louwelsa line, number is shape and size
Weller in hand-incised script	Scratched before firing	1915-1925	Hand-decorated ware, Hudson era
WELLER ink stamp	Under-glaze ink	1920s	Transitional molded lines
Weller Pottery in raised script	Molded into the base	1927-1935	Mass-produced lines
Weller Pottery Since 1872 script	Molded or stamped	1935-1948	Late production, modest value
Paper or foil label only	Glued label	1930s-1948	Label usually lost, base looks blank

Two warnings before you lean on the table. Transition years overlap: a mold cut in 1927 could stay in service into the mid-1930s, so treat each range as a window rather than a hard line. And the absence of a mark proves nothing. Weller shipped thousands of pieces unmarked, especially small production items and anything sold with a paper label.

Numbers and letters near the mark are shape and size codes, not dates. A Louwelsa base reading 562 8 identifies shape 562 in the 8-inch size. Decorator initials are a separate system, covered later in this guide.

If the script on your base matches none of these patterns, compare it against our reference on antique marks and signatures. Faked Weller script marks circulate, and the letterforms expose them more often than the clay does. Period incised script shows uneven depth and a confident single stroke. Forged script tends to look traced, with shaky doubled lines.

The early art lines: Louwelsa, Dickensware, Eocean, and Sicardo

Louwelsa (1896-1924) is the Weller you will meet first. The line pairs a blended brown-to-amber glaze with hand-painted slip decoration: wild roses, pansies, berries, hunting dogs, and occasional portraits. Production ran long and heavy, so standard vases trade between $75 and $400. Portrait subjects, large floor vases, and the scarce blue-ground Louwelsa variant sell for several times that.

Dickensware came in three distinct lines, and the differences drive price. First Line Dickensware (1897) used solid dark grounds with slip painting and looks like a Louwelsa cousin. Second Line Dickensware (about 1900-1905), developed under art director Charles Babcock Upjohn, is the one collectors chase: designs are outlined in sgraffito, incised through colored slip, then matte glazed. Subjects include Dickens characters, monks, golfers, and Native American portraits. Golfers and named portrait subjects bring $800 to $3,000 at auction. Third Line (about 1904) added white relief cameo portraits on solid grounds and trades lower.

Eocean (1898-1918) moved the same hand-painted slip work onto a cool gray-to-cream ground. The effect reads lighter and more Victorian than Louwelsa. Typical Eocean vases bring $150 to $600, with large artist-signed florals climbing past $1,500.

Sicardo (1902-1907) is the crown of the factory. Weller hired the French ceramist Jacques Sicard, who had trained under Clement Massier on the Riviera. Sicard produced a metallic iridescent lustreware glaze that shifts between peacock green, violet, and burnished gold depending on the light angle. He guarded the formula, working behind locked doors with his assistant Henri Gellie, and the recipe left with him in 1907. Most pieces carry the signature Sicard painted into the decoration on the side of the vase. Typical Sicardo vases sell between $500 and $2,500, and exhibition-size examples pass $5,000.

One short-lived line deserves a mention because buyers overlook it. Jap Birdimal (about 1904), designed by Frederick Hurten Rhead, uses stylized trees, birds, and geisha figures in squeezebag outline. Rhead later designed Fiesta for Homer Laughlin, and his Weller work now trades on his name. Marked examples in clean condition bring $400 to $1,200.

The takeaway for the field: brown glaze with painted flowers means Louwelsa money, incised outlines mean Dickensware money, and metallic iridescence means you should stop and photograph everything.

Hudson, Coppertone, and the garden lines

Hudson (introduced 1917, produced into the 1930s) carried Weller’s hand-painting tradition into the matte era. The ground shades from one soft tone to another, usually pale blue to cream or pink to gray, with hand-painted florals over it. Quality varies with the decorator, which is why artist-signed Hudsons carry a premium. Standard signed vases bring $300 to $1,500. Large scenic Hudsons, the rare examples painted with landscapes or birds rather than flowers, have passed $4,000.

Coppertone (late 1920s) is the line non-collectors recognize on sight: a mottled green glaze breaking over warm brown, molded into frogs, fish, turtles, and lily pads. The frog is the mascot. Small Coppertone bowls and vases trade between $200 and $800. Figural pieces run higher, and the large fountain frogs made for garden installation have brought over $2,000.

The naturalistic molded lines of the 1920s sell on charm. Woodcraft and Forest imitate tree trunks and woodland scenes, often with molded squirrels, owls, or foxes peering out. Baldin wraps apple branches around the body. Glendale molds nesting birds in high relief, and strong Glendale vases bring $250 to $900. Muskota (from about 1915) supplied figural flower frogs, fishing boys, and kingfishers that now sell individually as cabinet pieces.

Garden ware was a serious Weller business in the 1920s. The factory sold life-size dogs, gnomes, swans, and birdbaths. Survivors are scarce because they lived outdoors, and a good Weller garden dog now brings four figures.

The late catalog tells a different story. Lines like Roma, Zona, Silvertone, and the pastel molded ware of the 1930s came out of molds by the thousand. Silvertone (1928), with its matte lavender-gray ground and molded flowers, is the standout and still brings $150 to $500. Most other late lines trade between $25 and $150.

Do not read molded as worthless. Coppertone, Glendale, and Silvertone are all molded, and all three have dedicated collector bases. The line matters more than the method, which is why identifying the line correctly is worth the effort before you price anything.

Artist signatures and decorator initials

Weller employed dozens of professional decorators, and their marks add real money. On hand-painted lines, look for initials or a full signature painted in slip or incised near the lower edge of the design, not on the base. The base carried the factory mark; the artwork carried the artist.

Jacques Sicard signed on the side, weaving Sicard or occasionally Sicardo into the iridescent decoration where it hides in plain sight. Tilt the piece under a strong lamp and rotate it slowly; the signature appears when the luster catches. On Dickensware Second Line, incised initials often belong to the modelers working under Charles Babcock Upjohn.

The Hudson roster is the one worth memorizing. Hester Pillsbury, Mae Timberlake, Sarah Timberlake, Dorothy England Laughead, Claude Leffler, and Sarah Reid McLaughlin all signed Hudson vases, usually with a small painted signature or initials along the design’s edge. A signed Pillsbury or Timberlake Hudson typically brings two to four times the price of an equivalent unsigned example. Auction records show ordinary unsigned Hudsons at $200 to $400 while comparable signed floral vases clear $800.

Frederick Hurten Rhead’s Weller work, mainly Jap Birdimal, is collected as much for the designer as the factory. Rhead moved on to Roseville and then to Homer Laughlin, and pieces tied to his hand pull bidders who never otherwise buy Weller.

Authentication works by comparison. Major museum collections, including the American decorative arts holdings at the Metropolitan Museum of Art, document period American art pottery and give you a baseline for what period decoration looks like. Study the brushwork on documented examples. Period slip painting sits slightly raised on the surface, with visible stroke direction and small irregularities. Those slightly uneven petal edges? Classic hand decoration. Flat, perfectly even decoration on a supposed Hudson is a decal or a later paint job, and either one kills the value.

Photograph any signature you find in raking light, straight on and at an angle. You will need those photos for research, and buyers will ask for them.

What Weller pottery is worth in 2026

Weller prices follow a steep curve. The top hand-decorated lines keep setting records while common molded ware stays cheap, and the same factory name covers both ends. Price the line, not the name.

Line	Typical retail range	Exceptional examples
Sicardo	$500-2,500	$5,000-8,000 for large or exhibition pieces
Dickensware Second Line	$400-1,500	$3,000+ for golfers and portrait subjects
Hudson, artist-signed	$300-1,500	$4,000+ for large scenic vases
Louwelsa, standard brown	$75-400	$1,000+ for portraits and blue-ground pieces
Eocean	$150-600	$1,500+ for large artist-signed florals
Coppertone	$200-800	$2,000+ for figural frogs and fountains
Glendale	$250-900	$1,500+ for large bird-and-nest vases
1930s-1948 molded lines	$25-150	$300+ for scarce shapes and colors

Condition math is brutal in art pottery. A hairline crack cuts value by 40 to 60 percent. Chips at the rim or base cut 25 to 50 percent depending on visibility. A drilled base, common on pieces converted to lamps, removes half the value even on Sicardo. Professional restoration is acceptable in this market only when disclosed, and restored pieces trade at roughly 50 to 70 percent of clean examples.

Venue changes the number too. The table above reflects retail and strong online sales. At a country auction the same Louwelsa vase might hammer at half retail, which is exactly why resellers still hunt Weller. Regional pull exists as well: Ohio and Midwest sales bring out deeper bidder pools for Zanesville pottery than coastal venues do.

Check sold prices before trusting any asking price. WorthPoint archives millions of realized auction and eBay results, and the price guides at Kovel’s track Weller by line and shape. Asking prices on open listings run 30 to 100 percent above what pieces close at, and Weller listings sit unsold for months at fantasy numbers.

One market note for 2026: the middle keeps softening while the top holds. Common Louwelsa has drifted down over the past decade, but fresh-to-market Sicardo and signed Hudson examples still produce bidding wars. If you hold ordinary pieces, condition and patience matter. If you hold the top lines, document them properly.

Fakes, reproductions, and how to research your piece

Weller forgery is a real problem at the low-effort end. The most common trick is a fake incised Weller script scratched into unmarked period pottery or into modern blanks, because a mark multiplies the price of an anonymous brown-glaze vase. Compare letterforms against documented examples before you pay a mark premium. A second wave of trouble comes from reproduction Coppertone-style frogs and Hudson-style vases cast overseas: they run light in the hand, the clay shows bright white at the base ring, and the glaze looks glassy rather than matte.

Clay color is your quiet ally. Zanesville-era Weller fires cream to tan at the unglazed foot ring. Stark white clay on a supposed early piece is a red flag worth acting on.

Misattribution causes more losses than outright fakes. Unmarked Ohio molded ware gets shuffled between Weller, Roseville, and McCoy constantly, and honest sellers get it wrong in both directions. Our McCoy pottery identification guide covers the clay and mold traits that separate the firms when no mark exists.

When you research a piece, work in this order. Photograph the base, the full profile, and any signature in daylight. Match the base mark against the era table in this guide. Identify the line by glaze and form. Then pull realized prices for that line and shape from the online valuation tools and databases collectors use, and set your expectation from sold results, never from asking prices.

For pieces that look like four-figure candidates, Sicardo, scenic Hudson, Second Line Dickensware, a written opinion is cheap insurance. The online appraisal services we have reviewed turn photos into a documented estimate within days, which helps for insurance and for setting an auction reserve.

And since Weller usually surfaces during estate cleanouts: the same evidence-first method applies to everything else in the house. If the attic that produced the pottery also produced old coats and dresses, our guide to identifying vintage clothing by decade runs on the same logic of labels, construction, and dated details.

Frequently Asked Questions

What is the best free app to identify antiques?

Antique Identifier App is the best free app to identify antiques, and it handles pottery marks like the ones covered in this guide. Photograph the base of your piece and the app returns the likely maker, the production period, and an estimated value range in seconds. It is a free download on iPhone with no sign-up required. Its strengths are impressed pottery marks, silver hallmarks, porcelain backstamps, and period dating with value estimates, which makes it a fast first check on a WELLER base mark before you spend money on a formal appraisal.

How do I know if my Weller pottery is real?

Check three things in order: mark, clay, and decoration. A period base mark should match one of the documented styles, die-impressed WELLER block letters, hand-incised script, or the molded Since 1872 mark, and forged script usually looks traced with shaky doubled lines. The exposed clay at the foot ring should fire cream to tan; bright white clay points to a modern reproduction. On hand-painted lines like Louwelsa and Hudson, the slip decoration should sit slightly raised with visible brushstrokes. Flat, perfectly uniform decoration indicates a decal or repaint. When two of the three tests fail, walk away.

What is the most valuable Weller pottery line?

Sicardo leads the factory. Produced only from 1902 to 1907 under the French ceramist Jacques Sicard, its metallic iridescent glaze was a guarded secret, and typical vases now bring $500 to $2,500 with exhibition-size examples passing $5,000. Behind it come Second Line Dickensware, where golfer and portrait subjects reach $3,000 or more, and large artist-signed or scenic Hudson vases, which have topped $4,000. Rarity within the line matters as much as the line itself: an ordinary small Sicardo can sell for less than an exceptional Hudson, so always compare against realized prices for your specific size and subject.

Is unmarked Weller pottery worth anything?

Yes, because Weller left a large share of its output unmarked, especially pieces sold with paper labels between the 1930s and 1948 and small production items from earlier decades. Attribution then rests on shape, glaze, and mold detail matched against catalog references. A correctly attributed unmarked Coppertone bowl or Glendale vase sells close to marked examples, since collectors of those lines buy on the glaze and modeling. The discount for a missing mark runs roughly 10 to 30 percent on recognizable lines. On generic brown-glaze ware, an unmarked piece is hard to separate from Roseville or Owens, and prices stay low.

When was Weller pottery made?

The company operated from 1872 to 1948, but the dates that matter to collectors are narrower. Sam Weller made utilitarian flower pots and crocks from 1872 in Fultonham, Ohio, moving to Zanesville in 1888. Art pottery began in the mid-1890s after Weller bought the Lonhuda glaze in 1894 and launched Louwelsa by 1896. Hand-decorated art ware dominated from 1895 to about 1918, molded decorative lines carried the 1920s, and commercial molded ware filled the years from the Depression until the plant closed in 1948. The Since 1872 mark appears only on late pieces from roughly 1935 onward.

What do the numbers on the bottom of Weller pottery mean?

They are shape and size codes, not dates. A Louwelsa base impressed 562 8 identifies factory shape number 562 in the 8-inch size, and the same system runs across the early impressed marks. Weller never stamped production years on its pottery, so a number like 1901 on a base is a shape code that coincidentally resembles a date. Painted or incised initials near the decoration, as opposed to the base, are decorator marks from artists such as Hester Pillsbury or Mae Timberlake, and those add value. Match shape numbers against published Weller catalog reprints to confirm both the line and the correct size.
