Editorial interest 76/100 Selection signal · not a rating of the site

Cotapiece uses a coin photo for AI-assisted identification, then consults its catalog to give a cautious verdict and official mintage information.

Landing page captured for the 2026-10-23 issue.

For: Euro-coin owners checking commemorative 2 € pieces
Worth noticing: The upload is reduced in-browser; Cotapiece says it does not retain the image after analysis and Anthropic deletes it within 30 days.

Field notes

The workflow separates visual identification from the value judgment: an AI reads the photo, then Cotapiece’s catalog supplies the verdict and mintage figure. The current page highlights 36 commemorative €2 coins from 2025 and links to 18 articles responding to press claims about rarity. It says uploads are reduced in the browser before being sent to Anthropic, and that Cotapiece does not retain the image after analysis.
