Anyone care to try and figure this one out?

4 over a partially cut 8 or S?

Was looking before i read Robs post but was thinking start / part of an 8.

Almost looks like an upside down 5 without the top stroke.

Bonus points for the denomination - Rob you don't get to guess! LOL

Could be anything. A mistake just means a random unintended punch. Doesn't have to be a number or a letter, or even the right way up.

well its a groat, zoom out a bit sometimes its good to see it a little smaller

Groat it is. At smaller size it looks more like a "5", and thought I'd found the rare 1853 currency. Alas alack, no.
