MintLens
Every value shown with its evidence — never a bare number

Identify any coin.
Trust what it's worth.

Point your camera at a coin and MintLens identifies it in seconds — with a value backed by real sold comps, a grade with a confidence range, and a home for it in your collection. No black-box numbers, no guessing.

Sold comps behind every valuation

Everything a collector needs, nothing a marketer added

MintLens is built around one idea: show the work behind every answer. That shapes each feature, from how a coin is identified to how its value is calculated.

AI coin scanner

A guided two-shot capture — heads, then tails — feeds a deterministic identification model trained on 30,000+ coins. Same coin in, same answer out, every time.

Estimated coin value

Every value is the median of real sold listings from eBay and Heritage, with the comps linked so you can check the math yourself.

PCGS verification

Cross-check a slabbed coin's cert number against PCGS's own records.

NGC verification

Same lookup for NGC-graded coins — catch a mismatched label before you buy.

Coin community

Ask questions, share finds, and get a second opinion from other collectors.

Scan history

Every coin you've ever scanned, searchable, even the ones you didn't keep.

Favorites & watchlist

Track coins you don't own yet and get notified when comps move.

Fast recognition

Two photos in, a full identification out — typically under four seconds.

From photo to answer in four steps

No account required to try it. The full identification flow — capture, match, evidence — takes about the time it takes to read this sentence.

  1. 01

    Scan your coin

    Frame the coin inside the guide, heads then tails. No special lighting or macro lens required.

  2. 02

    AI identifies it

    MintLens matches your photos against embeddings from 30,000+ known coins and returns a deterministic result — same coin, same answer, every time.

  3. 03

    See the evidence

    Country, denomination, year, and mint, plus an estimated grade with a confidence range and the sold comps behind the value.

  4. 04

    Save or share it

    Add it to your collection with one tap, or post it to the community to get a second opinion from other collectors.

Recognition built to be checked, not just believed

Most coin-scanner AI is a black box: confident-looking output with no way to verify it. MintLens is built the opposite way — every step of the recognition pipeline is designed to be inspectable.

Deterministic matching
Coins are matched against stored embeddings, not a fresh guess each time. The same coin returns the same identification.
Seconds, not searching
Identification typically completes in under four seconds — no scrolling through lookalikes to self-diagnose.
Continuous learning
The reference set grows every week as new coins, varieties, and mint marks are added and verified.
Confidence-aware
Low-confidence matches say so, with retake coaching, instead of asserting an answer the model isn't sure of.

A collection manager that knows what you own

Every coin you scan can become part of a running inventory — organized, valued, and ready to reference the next time you're at a show or listing something for sale.

  • Portfolio value

    A running estimate of your whole collection, built from the same sold comps as every individual coin.

  • Sets & categories

    Group coins by series, country, or a set you're building — track completion as you go.

  • Favorites & wishlist

    Star coins you own and want to feature, or ones you're still hunting for.

  • Scan history

    Nothing gets lost — every coin you've scanned stays searchable, kept or not.

PCGSNGC

Verify a slab against the grading service itself

A cert number is only proof if it matches the issuer's own records. MintLens looks up PCGS and NGC certificates directly and shows you the population report, price guide, and full coin details tied to that number — so a mismatched label is a red flag you catch before you pay, not after.

  • Enter the cert number printed on the slab label
  • See the grade, designation, and population count on file
  • Compare it against what's physically in front of you

The story behind the 1933 Double Eagle is wild if you haven't read it

The 1933 Double Eagle was struck right as the US left the gold standard — every single one was ordered melted down, but a small number got smuggled out before that happened…

First time selling at a local coin show this weekend — any advice?

Finally clearing out some duplicates and lower-grade stuff I've upgraded from, table booked for Saturday. How aggressive is the haggling usually?

We built this from what already went wrong

Before writing a line of code, we read 500 recent reviews of the market's leading coin scanner and cross-checked them against independent expert testing. Three findings shaped every product decision in MintLens.
