See It In Action
One Photo, and You Know What You're Holding
Identification, grade-aware value, and fake flagging — from a single photo.
Full Feature Set
Built for What's Actually in the Shoebox
Coins, notes, cards, and comics live in the same collection — so they live in the same app, with the same honest numbers.
One Photo, Named
Point the camera and Provenance identifies the piece — date, mint, variety, issue — instead of making you already know what you have.
Grade-Aware Pricing
What it's worth raw, and what it's worth at every grade above that — with submission fees and the odds factored in, so "should I grade it?" has a real answer.
Fakes and Key Issues Flagged
Reprints, counterfeits, and the key issues worth a second look — surfaced before you pay for an original.
One Vault, One Total
Coins, notes, cards, and comics in a single collection with a running total — what the whole thing is worth, not just the last thing you scanned.
Value History
Watch each piece move over time instead of guessing whether that price you remember still holds.
Shareable Appraisal Card
Turn any find into a clean card worth sending — the collector's version of showing someone the good one.
Insurance-Ready PDF
Export the collection as a document an insurer will actually accept, itemized and dated.
Your Collection Stays Yours
Scans stay on your device. Nobody needs to know what's in your safe to tell you what it's worth.
Under the Hood
How the Numbers Are Derived
Comps labelled by their real source
Every dollar figure carries the wire value of where its comparables came from, and that value picks the wording: only data from eBay's sold-price API may be described as a sale — everything else reads "current asking prices" on the card, in the disclaimer, and in the VoiceOver label. An asking price cannot be rendered as a sale anywhere in the app.
No comps, no number
The valuation model is only ever shown the real listings that came back, and is told to reason over those alone. When the market returns nothing, the route sends explicit nulls and the app shows a "value pending" state instead of a figure — a guardrail test asserts the null rather than trusting the prompt.
Condition has no single-grade field
The condition type stores a low and a high label and nothing else, so a photo read is structurally incapable of expressing one certified grade. The server collapses a model that answers with one number into low == high, and the grading scale travels with the estimate so a coin can never come back graded on the card scale.
Grade ladder priced net of the real fee
"Should I grade this?" is answered by each hobby's actual scale — PCGS Sheldon for coins, PMG for notes, PSA for cards, CGC for comics — with that service's submission fee subtracted from every graded rung, so the upside shown is what would be left after paying. Outcomes are ranked in words rather than invented odds, because nothing in a photo supports a percentage.
How We Compare
Identification, Valuation, and the Vault in One Place
Marketplaces are where things sell; price guides are where values are published. Provenance is for the moment before either — working out what the thing in your hand actually is, and what it's plausibly worth, without already knowing the answer.
