This is the ONLY USPC crest & seal that I know of that is not the standard 1½" diameter (I have an oversized Burt from the '70s, but that hardly counts). This Brazilian roulette is 1¼" in diameter. Also note that instead of a square or rounded edge it has a chamfered edge for ease of pickup, I presume. The Peruvian rarity is there foir size comparison. Both sides of the roulette are shown.
