List one item per line. We'll auto-value each and save them to your account — sign in on iOS with the same email and your collection's waiting.
A multi-source valuation engine for cards, coins, watches, fine art, books and 20+ other collectibles markets. Drop in a barcode, a cert number, or a photo — get a transparent, methodology-backed number you can act on.
Tell us roughly what it is — we'll find a match.
Our blended engine has strong coverage in cards, coins, vinyl and books today. For other markets — comics, art, jewellery, sneakers, militaria, watches outside our reference set — we run a manual valuation and email it to you within 24 hours.

Your email becomes your Assay account the moment the iOS app launches — so the valuation we send you will already be saved there.
Assay provides market-based valuations, not certified appraisals. Values are estimates assembled from live multi-source data and may not be accepted by every insurer without further documentation. See our Pricing page for the insurance documentation pack tier.
We'll save this valuation to your collection and email you the full report at [email protected].
We can pull it all together — what you own, what each piece is worth right now, what's moving. We re-value automatically. Your call.
Most price tools show you one guess. Assay queries every authoritative source in the market and shows you how each one weighs in — so you can act on a number you actually understand.
Paste a description, ISBN, or grading cert number. We resolve it against PCGS, PSA, Open Library and 10+ reference databases.
We pull live prices from price guides (PCGS, PriceCharting, WatchCharts), marketplaces (eBay Browse + sold comps, Discogs) and your item's grading registry.
Each source is weighted by tier and recency. Live data is the spine; historical comps are the sanity check. Confidence band reflects how much your sources agree.
Branded PDF with cover, cert seal, watermark, per-source breakdown, comparables, methodology, and a signatory page for a credentialed assessor.
Twelve live integrations blending into one fair-value with a transparent confidence band. Every contributing source visible.
Each report ships with a signatory page so a licensed ISA / AAA / ASA appraiser can countersign for insurance, probate or estate work — we've done ~9/10ths of the evidence pack.
Unique cert seal + per-cert watermark on every page. Your numbers are archived at purchase — a re-download next year gives you exactly the same document.
Branded PDF in your inbox, with the full source breakdown, comparables, methodology and dated frame. A sealed copy is archived to your Assay account — ready to land in the iOS app the day it ships.
Assay provides market-based valuations, not certified appraisals. Insurers requiring a USPAP-compliant appraisal can use this report as the evidence pack and we'll introduce a licensed appraiser (ISA / AAA / ASA) to countersign on their own letterhead — reply to your delivery email to request it.
