AI coin grader: find your coin's value from a photo

Photograph the front and back of a coin or banknote. CoinGrader identifies it, estimates its grade on the 1 to 70 scale collectors use, and tells you roughly what it's worth and whether professional grading is worth the fee.

Real example result

1882 Morgan Dollar

G-4

United States, 1882, Philadelphia (no mint mark), silver dollar

Estimated value $33

Range $30 to $36. Value from the eBay sales and price guides found when it was graded.

Note: its 0.7734 oz of silver alone was worth about $50 on September 26, 2026, more than this July estimate.

Should you grade it? Probably not worth grading. Grading costs about $40 and would add about $9 of value.

Real result: one of our own test coins, graded July 13, 2026. Values change over time.

How the AI coin grader works

Three steps, no coin expertise needed.

Photograph both sides

Use your phone camera in good, even light. Fill the frame with the coin and avoid glare.
AI identifies and grades it

It reads the country, year, mint mark and type, then estimates the grade from wear, strike, surface and luster.

What you get in every report

Identification

Country, denomination, year, mint mark and series, for coins and paper money from any country.

Grade estimate

A grade on the 1 to 70 Sheldon scale used by PCGS and NGC, with separate scores for strike, surface, luster and eye appeal.

Value estimate

A value and a low to high range, with the sources used. Comparable sales are listed with their dates when we have them.

Grading recommendation

Whether paying a grading service is likely to pay off, based on the coin's value raw and graded and the cost of grading.

Condition notes

Marks, wear and other problems the AI spotted in your photos, shown on the coin.

Your collection

Every result is saved to your collection, and you can share a link to any report.

Speed and accuracy

Speed. Most results are ready in about a minute or two.

Accuracy. The grade is an AI estimate from your photos, not a certified grade. Sharp, evenly lit photos of both sides give the best results; blur, glare or a missing side can move the grade. Grading services like PCGS and NGC examine the coin in hand, so use CoinGrader to decide which coins are worth sending to them.
