First, I have to say this IS NOT MINE!
OK, I have a few old Spink Auction catalogues, but none as old as this. On the PCGS chatroom site there is a recent visitor that claims to have from his father's estate an 1848 Godless Gold Florin pattern that his dad obtained from a Spink 1974 LA Hilton Auction. Was there such a sale, and did it feature a gold pattern florin?
I certainly give pause to calculate its value if genuine!
