This is Charlton # NS-2A4 Courteau # 263. It has 4 leaves, the left leaf touches the F and a small tip, hard to see, is found between the the 3 more prominent leaves. On the reverse the stem of the thistle also helps to define this variety, it is long and has more of a point than some of the other varieties.
I think it would grade XF, VF30 for sure.
I was the under bidder on this one. Excellent buy!!
