The fastest way to find what your antique is worth is to identify its maker’s mark, then compare recent sold prices. Condition and demand set the value.
Start with the marks, not a guess
Every antique valuation begins with identification. You cannot price an object you cannot name. Find the marks before you think about money.
Turn the piece over. Makers signed their work on the base, the back rim, or an inside edge. Silver carries struck hallmarks. Porcelain carries a painted or stamped backstamp. Furniture often hides a stamp inside a drawer or on the back rail.
A maker’s mark narrows the field in seconds. Crossed swords on a porcelain figure point to Meissen, the German factory founded in 1710. A lion passant on a spoon confirms English sterling silver. An anchor beside it adds Birmingham as the assay office.
Marks also date the object. English silver carries a date letter that changes each year. A shield-shaped letter in the right alphabet can pin a London piece to 1899. Our antique marks and signatures guide breaks down each symbol in order.
Worn marks are normal. Decades of polishing soften the stamps on silver and the gilding on porcelain. Use raking light from a desk lamp. Hold the piece at an angle so the shallow stamp throws a shadow. A 10x jeweler’s loupe reveals letters the naked eye misses.
Some pieces carry no marks at all. Country furniture, early American coin silver, and folk pottery were rarely signed. Here you read construction instead. Hand-cut dovetails, genuine shrinkage cracks, and oxidized secondary wood all signal real age. The crusty surface collectors call patina is hard to fake convincingly.
The maker decides the ceiling on value. A signed Rogers silverplate set sells in a predictable band. An unsigned set in the same pattern sells for less, because buyers cannot confirm who made it.
Write down everything you find: the words, the symbols, the numbers, and where each appears. That record is the search key for every price guide and auction archive you use next.
The four factors that set every antique’s price
Four variables decide nearly every antique price: maker, age, condition, and demand. Learn to weigh them and you can estimate value before you ever open a price guide.
Maker sets the ceiling. A vase by a documented factory outsells an anonymous one of equal beauty. Buyers pay for names they can verify. Tiffany, Meissen, Gorham, and Rookwood all carry a premium for the mark alone.
Age matters, but not the way most people assume. Old does not automatically mean valuable. A common Victorian pressed-glass dish from the 1890s can sell for under twenty dollars. A 1955 studio ceramic by a named potter can bring several hundred. Rarity and maker beat raw age almost every time.
Condition is the great multiplier. A hairline crack, a replaced handle, or a later monogram can cut value by half or more. Collectors pay top prices only for honest, original surfaces. We cover the metal side of this in our silver melt value versus antique value guide, where damaged pieces often fall back toward scrap price.
Demand is the factor people forget. Value lives where collectors are actively buying. A category can sit flat for years, then spike when a new wave of buyers arrives. Mid-century modern furniture climbed sharply after 2010 as a younger market discovered it.
The table below shows how each factor pushes price up or down.
| Factor | What it measures | Effect on price |
|---|---|---|
| Maker | Who produced the piece, confirmed by marks | Sets the ceiling; a named maker can double value |
| Age | Period of manufacture | Helps only when paired with rarity or a maker |
| Condition | Originality and damage | The multiplier; damage can halve value fast |
| Demand | How many collectors want it now | Decides the floor; cold categories sell slowly |
Metal content adds a hard floor for some objects. Gold and silver carry intrinsic melt value no matter how plain. A worn 10K, 14K, or 18K gold piece is worth its weight even when its design is dated.
Read all four factors together. A famous maker with heavy damage and no buyers is worth less than a modest maker in perfect condition that everyone wants.
How to check what antiques actually sold for
The single biggest valuation mistake is trusting asking prices. What a seller wants and what a buyer paid are different numbers. Always price from completed sales.
Asking prices are wishes. Anyone can list a plate for five hundred dollars. That number tells you nothing until someone pays it. Sold prices are facts, recorded after money changed hands.
Start with eBay. Run a search, then filter to “Sold Items.” You will see the real closing price and the date. Look for at least three to five recent sales of the same maker and pattern. Ignore the single outlier that sold high; price toward the cluster in the middle.
Subscription archives go deeper. WorthPoint holds hundreds of millions of past sales across marketplaces and auctions, with photos and final prices. Kovels maintains a respected price guide and a searchable mark database built over decades. Both are paid, but a single accurate valuation often justifies a month of access.
Auction house archives are free and authoritative for higher-value pieces. Major houses publish realized prices, including the buyer’s premium, going back years. For fine art glass, signed silver, or Asian ceramics, these records are the gold standard.
The table below maps each source to the job it does best.
| Source | Best for | Cost |
|---|---|---|
| eBay sold listings | Everyday antiques and collectibles | Free |
| WorthPoint | Deep archive with photos and marks | Subscription |
| Kovels | Price guide plus mark identification | Subscription |
| Auction house archives | Fine and high-value pieces | Free |
Match like with like. A teapot with its original lid is not comparable to one missing the lid. A first edition in its dust jacket can be worth ten times the same book without one. Filter your comparables down to pieces in the same condition as yours.
Watch the calendar too. Markets move. A silver pattern that sold for two hundred dollars in 2019 may sell for more today after the recent run-up in metal prices. Weight your estimate toward sales from the last twelve months, and treat anything older than five years as a rough guide only.
Not sure what you’ve got?
Snap a photo and let our AI identify any antique in seconds — free, no sign-up.
Identify on iPhone →Learn MoreIdentify and value it instantly with your phone
You no longer need to mail photos to an expert and wait a week. A phone camera and the right app can identify most antiques in seconds and return a working value range on the spot.
The method is simple. Photograph the whole object in even, natural light. Then take a sharp close-up of the maker’s mark, the backstamp, or the hallmark. Clear images of the marks matter far more than a pretty overall shot.
Lighting is the one variable you control. Shoot near a window in daytime. Avoid direct flash, which blows out the shallow detail of a stamp. If a mark sits in a recess, tilt the piece until the engraving catches the light.
Image-recognition tools compare your photo against large reference databases of marks, patterns, and forms. A good app reads a porcelain backstamp, names the factory, suggests a date range, and pulls a value estimate from recent sales. What once took an appraiser now takes a tap.
A real example shows the speed. Photograph the base of a dinner plate, capture the backstamp, and an app can return “Limoges, France, early twentieth century” with a comparable value range in under a minute. From there you confirm the exact pattern against sold listings.
Apps are strongest on marked, catalogued objects: silver hallmarks, porcelain maker marks, pressed-glass patterns, and pottery stamps. They are weaker on unmarked folk pieces and one-of-a-kind art, where human judgment still wins.
Use the app as your first pass, not your final word. It narrows thousands of possibilities to a short, named list in seconds. You then confirm the match against sold listings and the deeper databases in our digital antique valuation tools roundup.
Treat the value estimate as a starting range, not an appraisal. The number reflects what similar pieces are selling for right now, not a guaranteed payout. The free option removes every barrier to a fast first answer, so point, shoot, and read the result before you decide whether a piece is worth a deeper look.
Condition grading, and what collectors quietly deduct for
Condition decides where a piece lands inside its value range. Two identical objects can sell for very different sums when one is mint and the other has been repaired. Learn the deductions collectors make automatically.
Grade against original, undamaged condition. Every flaw is a subtraction from that baseline. The bigger and more visible the flaw, the deeper the cut.
Chips, cracks, and breaks hit hardest. A hairline crack in porcelain, even a tight one, can remove a third to half of value. A visible chip on a rim does the same. Restoration helps display but rarely restores full price; sophisticated buyers detect and discount repairs.
Surface wear matters on silver and gilt. Heavy polishing thins silver and softens hallmarks. Worn gilding on a porcelain rim or a clock dial lowers grade. An original surface, even with light age, beats an over-cleaned one.
Alterations and additions reduce value too. A monogram added later, a replaced handle, a married lid from another piece, or a re-drilled lamp base all count against authenticity.
The table below shows typical deductions collectors apply.
| Condition issue | Typical impact on value |
|---|---|
| Hairline crack in porcelain | Down 30 to 50 percent |
| Visible chip or rim flake | Down 25 to 40 percent |
| Professional repair or restoration | Down 20 to 40 percent |
| Later monogram or engraving | Down 10 to 25 percent |
| Heavy polishing or worn gilding | Down 10 to 20 percent |
| Replaced or married part | Down 30 to 60 percent |
Sets carry their own rule. A complete set of twelve commands a premium per piece; a partial set of nine sells at a discount, because buyers want to serve a full table. The same logic applies to flatware services and tea sets.
Document condition honestly when you value or sell. Photograph every flaw in good light. Buyers trust sellers who disclose, and an honest description protects your price. Hiding damage almost always backfires when the piece arrives and the flaw is found.
When you can skip the appraiser, and when you truly need one
For most everyday antiques, you do not need a paid appraiser. Marks, sold listings, and an app give you a reliable working value. But some situations demand a certified, written appraisal, and knowing the difference saves money and protects you.
You can self-value with confidence when you are buying at a fair, selling a common piece online, or simply curious what an inherited object is worth. The stakes are low and the data is public. A short list of comparable sold prices answers the question.
You need a professional when money or law is involved. Insurance coverage for a valuable collection requires a written appraisal an insurer will accept. Estate settlement and probate often require formal valuations. Charitable donations above a set threshold need a qualified appraisal for the tax deduction to stand. Dividing an estate fairly among heirs benefits from a neutral expert number.
Choose the right kind of valuation. An appraisal for insurance lists replacement value, usually the highest figure. An appraisal for estate or resale lists fair market value, what the piece would actually fetch. The two numbers can differ widely for the same object.
If you are weighing online services against a local appraiser, our best online antique appraisal sites comparison breaks down cost, turnaround, and accuracy for each option.
Free institutional resources can deepen your own research before you pay anyone. Museum collection databases show documented examples with full attribution. The Smithsonian collections, the Metropolitan Museum of Art, and the Victoria and Albert Museum all publish searchable records you can compare against your piece.
A reasonable workflow is to self-value first, then escalate. Identify the maker, check sold prices, and grade condition. If the working value is modest, you are done. If the number is high, or if insurance, tax, or a court is involved, take your research to a credentialed appraiser and let the written report do the heavy lifting.
Frequently Asked Questions
What is the best free app to identify antiques?
Antique Identifier App is the best free app to identify antiques. It runs on iPhone, downloads free with no sign-up required, and identifies a piece from a single photo. Point it at a silver hallmark, a porcelain maker mark, or a pressed-glass pattern, and it returns the likely maker, an estimated period, and a value range drawn from recent sales. It is strongest on marked, catalogued objects, where it reads the stamp and matches it against a large reference database in seconds. For unmarked folk pieces or one-of-a-kind art, treat its answer as a starting point and confirm against sold listings before you rely on the number.
How can I find out what my antique is worth for free?
You can find what your antique is worth for free using three steps. First, photograph the maker’s mark and identify the maker and approximate date. Second, search eBay and filter to sold listings to see what identical pieces actually closed at, not what sellers are asking. Third, grade the condition honestly, since a crack or repair can cut value by a third or more. Free auction house archives also publish realized prices for higher-value items. A free identification app speeds up the first step by naming the maker from a photo. Together these cost nothing and answer most everyday valuation questions without a paid appraisal.
Do I need a professional appraiser to value an antique?
Not for most pieces. If you are buying at a fair, selling a common item online, or simply curious about an inherited object, sold listings and an app give you a reliable working value at no cost. You need a certified appraiser when money or law is involved: insurance coverage, estate and probate settlement, dividing an estate among heirs, or a charitable donation above the IRS threshold that requires a qualified appraisal. Note that an insurance appraisal lists replacement value, usually the highest figure, while an estate or resale appraisal lists fair market value. Self-value first, and escalate to a professional only when the stakes are high.
Where can I see what antiques actually sold for?
Start with eBay and filter to sold listings, which show real closing prices and dates for everyday antiques. For deeper research, WorthPoint holds hundreds of millions of past sales with photos and final prices, and Kovels offers a long-running price guide plus a mark database. For fine and high-value pieces, major auction houses publish realized prices, including the buyer’s premium, going back years for free. The key in every case is to compare sold prices, not asking prices, and to match condition closely. A piece with its original lid is not comparable to one missing it, and recent sales matter more than old ones.
How does condition affect an antique’s value?
Condition is the biggest multiplier in antique value. Grading always starts from original, undamaged condition, and every flaw subtracts from that baseline. A hairline crack in porcelain can remove 30 to 50 percent of value, a visible chip 25 to 40 percent, and a professional repair 20 to 40 percent. Later additions such as an engraved monogram or a replaced handle also lower the price, as does heavy polishing that thins silver and softens hallmarks. Complete sets carry a premium, while partial sets sell at a discount. Always document flaws honestly with clear photos, since buyers trust disclosure and an accurate description protects your final price.
Why are two identical antiques priced so differently?
Two identical-looking antiques can carry very different prices for several concrete reasons. Condition is usually the first: one may have a hidden hairline crack or a later repair that halves its value. Marks matter next; a clearly struck maker’s mark confirms attribution, while a worn or absent mark forces a discount. Provenance can add value when an object has documented history or a notable former owner. Completeness counts too, as a full set outsells a partial one. Finally, timing and venue play a role, since the same piece sells higher at a specialist auction than at a general estate sale. Together these explain most price gaps.
