Pricing antiques for resale means layering comparable sales, condition grades, and market demand into one defensible number. Here’s the dealer framework. Get this wrong and you either leave money on the table or price yourself into a permanent display piece.
Why pricing antiques is different from pricing anything else
Most products have a manufacturer’s suggested price. Antiques have exactly zero of those.
Every piece is one-of-a-kind in terms of age, condition, provenance, and regional demand. A Georgian silver cream jug worth £280 at a Bath market might fetch £520 at a London silver fair. Same piece. Different room.
Any seasoned collector knows the market is fragmented on purpose. Dealers who understand that fragmentation profit from it. Dealers who ignore it get burned.
Pricing is also not static. Trends shift. What the Smithsonian’s American history collections classify as significant Americana one decade becomes mainstream and overproduced the next. Staying current matters as much as knowing history.
The framework below gives you a repeatable method. It won’t replace experience. It will keep you from making rookie mistakes on expensive pieces.
Step 1: Identify before you price (this is non-negotiable)
You cannot price what you cannot identify. Full stop.
Before any number touches paper, you need to know: maker, period, material, and country of origin. Skipping this step is how dealers accidentally sell a rare piece of Meissen for earthenware money.
For silver, look for hallmarks. British silver carries date letters, assay office marks, and maker’s punches. Our guide to identifying pewter vs. silver covers the quick field tests that separate profitable silver from decorative white metal.
For marks across all categories (porcelain backstamps, furniture maker’s labels, bronze foundry stamps), the antique marks and signatures identification guide is the most complete starting point I know.
For period dating on furniture, the construction details matter more than the style. Dovetail spacing, secondary woods, tool marks: those slightly uneven chisel lines on a drawer bottom tell you more than the cabriole leg profile ever will. Cross-reference what you find against the antique furniture periods chart 1600–1940.
Only once you know what you have can you find meaningful comparables.
Step 2: Build your comparable sales baseline
A comparable sale (a “comp”) is a recently sold item that matches yours in maker, period, condition, and size. Not listed. Sold.
Listing prices are fantasy. Sold prices are data.
Where to find sold comps:
- WorthPoint: the largest archive of sold auction and dealer prices. Subscription-based but worth every penny for active dealers.
- Kovels: strong on American pottery, glass, and silver. Free tiers available.
- eBay completed listings: filter to “Sold Items” only. Ignore active listings entirely.
- Major auction house archives: Christie’s, Sotheby’s, and Bonhams publish realized prices online.
- Live auction floor results from regional houses in your category’s strongest market.
Gather at least three comps before setting a number. Five is better. Ten is ideal for high-value pieces.
When comps vary wildly, investigate why. A wide spread usually means condition differences, provenance, or a one-off bidding war. Outliers in either direction skew your baseline. Drop the top and bottom comp and average the middle range.

Condition is the single biggest variable between two identical pieces. A mint-condition piece can command 2–3× the price of a damaged equivalent.
Dealers use a rough five-tier condition scale. Here’s how it maps to pricing:
| Condition Grade | Description | Price vs. Mint Baseline |
|---|---|---|
| Mint / Museum | No wear, original finish, complete | 100% (baseline) |
| Excellent | Minor surface wear, fully functional | 75–90% |
| Good | Visible wear, no structural damage | 50–70% |
| Fair | Chips, cracks, repairs, missing elements | 25–45% |
| Poor | Major damage, heavy restoration | 10–20% |
Apply this multiplier to your comp baseline. If comps cluster around £400 for a mint example and your piece grades “Good,” your condition-adjusted starting point is £200–£280.
For silver specifically, original patina preservation matters enormously. A piece that’s been aggressively polished to bright mirror finish has lost the aged surface that collectors pay premiums for. Those slightly uneven rim details on late Georgian hand-hammered pieces? Polishing them to uniformity destroys evidence of hand craftsmanship and tanks the value.
Repairs are not automatic deal-breakers, but they must be disclosed and priced accordingly. Invisible restoration on ceramics can be detected under UV light. Always check before you price and before you sell.
Step 4: Layer in demand, venue, and your margin
Your condition-adjusted comp baseline is not your final price. It’s your anchor. Three more factors move the number.
Market demand is category and timing specific. The Metropolitan Museum of Art exhibitions regularly spike collector interest in specific periods. A major show on Japanese decorative arts sends netsuke prices upward for 12–18 months. Watch what the major institutions are spotlighting.
Venue premium is real and significant. The same piece commands different prices in different rooms:
- Specialist antique fair: highest prices, most educated buyers
- General antique mall: mid-range, slower turnover
- Online marketplace (eBay, Etsy, Ruby Lane): price-sensitive buyers, global reach, shipping risk
- Auction house: unpredictable, can go high or low, fees reduce net
Build your venue into the price from the start. If you’re listing on a platform that takes 15% plus payment fees, your listed price must absorb those costs and still hit your margin target.
Your margin depends on your cost basis. Know your landed cost: purchase price plus any restoration, cleaning, research time, photography, and transport. A minimum 40% gross margin is a reasonable dealer floor. High-demand, hard-to-source categories can support 60–80%.
For pieces where melt value is a factor (primarily silver and gold), understand which floor protects you better. The silver melt value vs. antique value guide breaks down when spot price matters and when collector premium dominates.
Step 5: Sanity-check with a professional appraisal on high-value pieces
For any piece where your comp baseline lands above $500, a professional appraisal is worth the cost.
An ISA (International Society of Appraisers) or AAA (American Society of Appraisers) certified appraiser carries weight with insurance companies, estate attorneys, and serious buyers. Their written opinion protects you legally and gives buyers confidence.
Appraisals also catch authentication problems before they become expensive mistakes. The Victoria & Albert Museum’s collections database is a useful free reference for British decorative arts. Cross-check your piece’s design elements against documented examples before committing to a price.

One caution: never use a dealer’s “free appraisal” as your pricing basis if that dealer is also a potential buyer. The conflict of interest is obvious. Pay for independence.
Common pricing mistakes that cost dealers money
Twenty years in this field means I’ve made most of these mistakes personally. Learn from the list.
Pricing from listing prices, not sold prices. A £1,200 listing proves nothing. A £680 sold result tells you exactly what the market will bear.
Ignoring regional demand. Blue-and-white transferware sells faster and higher in New England than in Texas. Art Deco jewelry moves faster in coastal cities. Know your buyer pool.
Over-restoring before sale. Cleaning, repairing, and refinishing can destroy value faster than damage does. When in doubt, leave it alone and disclose condition honestly.
Anchoring to purchase price. What you paid is irrelevant to what the market will pay. Sunk-cost pricing is how inventory sits for years.
Underpricing rare pieces to move them quickly. Rare pieces need patient buyers, not discounted prices. Price correctly and wait for the right collector.
Ignoring provenance documentation. A piece with a documented ownership history (receipts, photographs, exhibition records) can command 20–40% above an undocumented equivalent. Keep every scrap of paper that came with a piece.
For gold pieces specifically, understanding hallmark grades changes your entire pricing calculus. The gold hallmark identification guide covering 10k, 14k, and 18k explains the grading system and its direct effect on value.
Frequently Asked Questions
How do I find comparable sales for antiques I want to price?
Use sold listings rather than active listings. WorthPoint archives millions of realized auction prices. eBay’s completed listings filter (set to Sold Items only) shows real transaction data. Kovels is strong for American pottery and glass. Major auction houses (Christie’s, Sotheby’s, Bonhams) publish realized prices in their archives. Gather at least three to five comps before setting your number.
What percentage markup do antique dealers typically use?
Most retail antique dealers work on a 40–100% gross margin above their landed cost, which includes purchase price, restoration, transport, and overhead. High-demand, hard-to-source categories can support margins above 100%. Consignment arrangements typically pay sellers 50–60% of final sale price. The right margin depends on your cost basis, venue fees, and how quickly you need to turn inventory.
Does restoration increase or decrease an antique’s value?
It depends entirely on the category and the quality of the restoration. For furniture, original finish almost always commands a premium over refinished pieces. For ceramics, invisible professional restoration can maintain value, but must be disclosed. For silver, aggressive polishing that removes original patina typically reduces collector value. The rule of thumb is: disclose everything, restore as little as possible, and never restore without researching how buyers in that category respond.
How does venue affect antique pricing?
Significantly. Specialist antique fairs attract educated collectors willing to pay full market value. General antique malls attract browsers expecting deals: expect 15–25% lower realized prices. Online platforms reach a global audience but attract price-sensitive buyers and carry platform fees of 10–15% plus payment processing. Auction houses are unpredictable. Premium pieces can exceed expectations, common pieces can fall flat, and seller fees reduce your net 10–25%.
When should I get a professional appraisal instead of pricing myself?
Get a certified appraisal from an ISA or AAA appraiser for any piece where your comp baseline exceeds $500, for pieces with unclear provenance or authentication questions, and any time insurance, estate, or legal documentation is involved. Professional appraisals also protect you if a buyer later disputes authenticity. For online options when in-person appraisal is impractical, specialist remote appraisal services exist for most major antique categories.
