Interesting. The holder says J-1627, which, according to my Judd book, is the same as J-1626, but struck in "silver" instead of "goloid." I suppose 1626 vs 1627 is kind of a judgement call, since one of the reasons the goloid alloy wasn't chosen for regular coinage is the difficulty of telling the gold content without resorting to precise elemental analysis. Also, top pop (3/0)! Cool!
