How Rare Is Your Coin?

Population is the total number of certified examples IGA has graded for a specific coin reference — broken down by every grade we've assigned. It does not represent the total number of that coin ever made; it represents how many have been authenticated and graded by IGA.

Low counts can mean genuine rarity, low collector interest in submitting that piece to IGA, or simply that few examples have been certified to date. Older and medieval pieces typically have lower counts than modern commemoratives.

Population data refreshes automatically as new certificates are issued. The "Last Updated" timestamp on this page reflects the most recent grading run.

A grade (e.g., MS 65) describes the coin's overall condition on the 1–70 Sheldon scale. A designation (e.g., +, DCAM, PL, Star) is an additional qualifier IGA may apply — for example, DCAM marks Deep Cameo contrast on a proof; + marks an example notably above its assigned grade.

Use the search and filter controls above. Filter by country and period to narrow the list, then look for your coin by year and denomination. Once you open a coin's detail page you can copy its reference code for future lookups.
