A clearer look at a richer past
Every coin has a story.
Compare possible matches, visible clues, historical context, and next checks from what your coin photo shows.
A provisional reading. Not authentication. Not grading. Not a price appraisal.
How it works
One photo is enough to begin
Front — Required
A sharp photo of the front face, with the whole rim and lettering in frame.
Back — Optional
The reverse can add useful context, then you compare clues and next checks.
Tip The edge, if you like
A rim close-up can show reeding, thickness, and seams — helpful, never required. Read the photo guide

What it may suggest
- A possible coin type or period
- Other possibilities to explore

Frequently asked questions
Can a photo identify or authenticate a coin?
A photo can support a provisional visual reading. It cannot authenticate a coin or establish its grade, condition, rarity, or market value.
Do my photos get sent as soon as I choose them?
No. Choosing a photo keeps it in this page. You decide whether to submit; selecting Continue to analysis sends the request through this site's Worker to Qomza.
How long is submitted information retained?
See the Privacy page for the retention period and details about what a submission includes.
Which photo types can I upload?
JPG, PNG, and WebP are accepted. The reverse side and the short note are optional. If your photo is HEIC, export or share it as a JPEG from your photo app first.
