🔍 Coin Detective

Identify errors in coin specifications: For accurate verification, the Precious Coin Tester app relies on precise coin specifications. However, official parameters may not always match real-world measurements. You can help improve our database by reporting discrepancies. Report any weight error (>3%), diameter error (>0.3mm), or purity error (>1%) in our catalog. Each verified report earns you Precious Points while enhancing accuracy for all users.

📚 Collection Builder

Add missing coins: Our extensive coin database is updated yearly, but many valuable coins around the world are still missing. You can help expand our collection by adding coins from previous years. To submit a new coin, send us an email including its photos, diameter, weight, purity, and a recorded test in the app. Each approved entry earns you Precious Points while enriching resources for stackers and collectors worldwide.
