I was second high bidder on the coin which is a known variety from my book GNL # 1805-O:J/R:MoJJ-001. I am aware of only three examples of this same die type - non of which are in my own collection. It is a Contemporary Circulating Counterfeit.
I noticed today for the first time, that Heritage has finally allowed a Charles IV Mexican colonial contemporary counterfeit to be advertised as a counterfeit in one of their sales.
