1856-S/S Seated Liberty Quarter. Large S over Small S. PCGS graded EF-45 In special PCGS Ship of Gold holder which contains One Pinch of Gold Dust recovered from the S.S. Central America treasure.<BR>Special PCGS number 803499.45/38277449. Listed in the Red Book. The S over S mintmark blunder is the result of the much smaller dime mintmark for San Francisco being pressed into the quarter die, the engraver realized the boo boo and swapped up to the much large Quarter "S" mintmark. The placement wasnt quite perfect so the underlying small S can be easily seen, especially on this high grade coin. Mint blunders like this are always out there to delight collectors, as errors like this are few and far between, but always "humanize" the whole process of producing coins into a way which makes us all relate to them in a comforting way.
