Was getting rid of some small change in the work vending machine. It must have been out of dollar coins because it was spitting out 50c pieces instead. I noticed a 50c 2020 JC effigy. Looking at Numista it seems there were none minted for circulation. Is this correct? If so, someone's busted up a set for loose change. Maybe the mintage figures haven't been released yet. Unfortunately no 1977 CoA was forthcoming.
