I have acquired a William & Mary shilling of 1693, on which the 3 appears to be struck over a 0 or more likely a misplaced 6, given that 1690 shillings were not struck. I know a rare 9 over 0 version exists, but has anyone come across a 3 over 0/6 such as this? The condition is not brilliant – less than fair, so do any of you out there have a better one to confirm the overstrike and indeed the final digit? Any comments?
