Is there something special about the silver ones? I have a bunch of brass SC tokens in my game (various images) and then there's a bunch of solver ones with the same drawing on all of them (a bank I think). My magic credit slot is adjusted for the brass ones, and the silvers are a hair too big to fit, so I excommunicated them from the pile for now. This is a domestic game, but I have no idea where its tokens came from (we got the whole shebang at a USAA auction 12 years ago)
