Shoot Eric, I'm on the wrong machine at the moment. I'll try to correct the situation when I employ the alternate mechanism later this evening.
Draper Mint made this round in the 1980's under the branding name of Swiss of America, which was located in Draper, Utah. These rounds are considered rare. The smaller 23.5 mm round is 1/4" thick. The larger round is 39 mm.
I'm curious what makes 1926-1995 "vintage." Seems like an odd date range. Thailand 20 baht, 36th Anniversary of birth of Rama IX (1963), commemorative issue, 20g 35mm .750.
