"What's it worth?" has an honest answer, and it isn't a number anyone can hand you — it's a method you run in about an hour. Real value is what informed buyers actually pay for genuinely comparable pieces, and that evidence is public. This guide is the method, start to finish, and it's the same one this site uses in place of the invented prices that infest this hobby.
Why we never quote values — and why that helps you
Any number printed on a page begins dying immediately: markets move, condition dominates, and no two antiques are truly identical. Sites that tell you your item "is worth $400" are guessing for clicks, and the guess anchors you into either giving a piece away or pricing it into unsellability. The method below replaces the guess with evidence you gather yourself — which also means you can rerun it next year, on the next piece, forever.
Step one: finish the identification
Value research on an unidentified object is astrology. Before pricing anything, you need the piece's family, function, era, any maker evidence, and an honest condition read — the sequence taught across this site, from the collecting guide through maker marks and bottle dating. Every attribute you pin down multiplies the quality of the comparables you'll find; "old medical tool" comps against junk, while an identified instrument comps against its actual market.
Step two: sold listings, not asking prices
The center of the method: on eBay, search your identified piece, then filter to Sold Items. Asking prices are wishes — the same object can sit listed at a fantasy number for years — but sold listings are transactions: real buyers, real money, dated. Work the sold results like a researcher: search under every name the piece goes by (the vocabulary problem is real — pharmacy, apothecary, chemist, drugstore all tag the same bottle), note the spread rather than a single sale, and open the listings to compare condition and completeness against yours honestly. One outlier sale is an anecdote; a cluster of sales for comparable pieces is a market.
The Evidence Base
Run the method now
Search your piece's category, then switch the filter to Sold Items and read the last few months of transactions — this is the primary evidence every honest appraisal in this field starts from.
Open the category and filter to sold →Step three: weigh the comparables
Raw comps need adjustment, and this is where identification pays. Condition and completeness dominate: a full cased set against your incomplete one, a labeled bottle against your unlabeled one, an outfit with its paperwork against your bare device — these are different markets, and the sold spread will show the gap explicitly if you pull comps from both sides of it. Documented makers and provenance move pieces into stronger comp pools. And recency matters: weight the last year over older sales, because this market moves like any other.
Identification Card
- What to look for
- A cluster of recent sold transactions for pieces matching yours in identification, condition, and completeness — with the spread, not a single number, as the finding.
- Commonly confused with
- Asking prices, price-guide figures of unknown vintage, insurance appraisals (a different, higher standard serving a different purpose), and the one spectacular outlier sale.
- How to confirm
- Multiple search vocabularies, Sold filter, listings opened and compared attribute by attribute, spread recorded with dates. Rerun before any significant transaction — evidence expires.
- What it isn't
- A guarantee. Comparable evidence estimates what a piece is likely to bring; the next auction can still surprise in either direction, and honest research prices the probability, not the promise.
Step four: widen the evidence when it matters
For significant pieces, eBay's sold data is the floor of the research, not the ceiling. Specialist auction houses publish realized prices for the top of this market, and their archives show what documented, exceptional pieces bring in front of the field's serious money. Dealer prices at specialist shows mark the retail layer — what vetted, guaranteed pieces sell for, which is legitimately above raw-market comps. And for the rare piece beyond all of this, a formal appraisal from a qualified appraiser is the professional instrument built for the job; what this method gives you is the literacy to commission and read one intelligently.
Reading the answer honestly
The method usually returns one of three findings. Most often: your piece is common, the sold spread is modest, and the honest response is to enjoy it or price it to sell — the finding nobody clicks for and everybody needs. Sometimes: the spread is real and your piece sits in its upper half on condition or completeness, and now you know why and can say so with evidence. Rarely: the comps are thin because the piece is genuinely uncommon — which is when the wider evidence of step four, and possibly professional appraisal, earns its cost. All three findings share one property the invented numbers never have: you can show your work.
Keep the research
Save your comps — screenshots or links, dated, filed with the piece's photographs and identification notes. The file prices your insurance conversation, answers a future buyer's "how did you get that number," and hands your eventual estate a valuation method instead of a mystery. In a hobby drowning in fabricated prices, a collection that carries its own evidence is worth more, in every sense, than one that doesn't.
Pricing to sell versus pricing to know
The same evidence serves two different decisions, and it's worth being clear which one you're making. Pricing to know — for insurance schedules, estate planning, or curiosity — reads the middle of the sold spread and files the research. Pricing to sell adds strategy: position near the spread's lower-middle for a timely sale, or at its top with patience and superior photographs if your piece's condition genuinely earns it, and let the listing cite its own comparables — "recent sold examples in this condition" is the single most trust-building line a listing can carry. Buyers run this same method in reverse, and a price that survives their check is a price that closes.
Frequently asked questions
How do I find out what my medical antique is worth?
Identify it fully, then research sold — not asking — prices for genuinely comparable pieces on major marketplaces, adjusting for condition and completeness. The spread of recent real transactions is the honest answer; any site handing you a single number without your piece in hand is guessing.
Why are sold listings better than asking prices?
Asking prices are wishes that can sit unmet for years; sold listings are completed transactions between real buyers and sellers. Only transactions measure a market.
