To all the experts out there I was going through some wheat coins and I found a 1956 D where the top of D is touching the bottom tail of the 9 is that unusual or a common occurrence? Thanks
Those mint marks were punched into the dies by hand(until 1990) so there was a pretty big target zone. Not unusual at all.
That's right. Mintmark location varied from one die to the next because the mintmarks were hand-punched then.
