482 Poké Lids across Japan's 47 prefectures. Every one you hold is stamped; the empty rings are still out there.
Sign in with Google to stamp the medals you have, see the ones you're missing and list your duplicates for trade.
Each square is a prefecture, placed roughly where it sits in Japan. The number is how many lids it has and how many you hold.
