1920S with a rpm does anyone agree with the rpm on this coin I know they can be very tricky but I went to variety vista best I can tell it has the S/S rpm
From those images I am not seeing a re-punch to the North, and the listed RPM on Vista appears to be little further right than your example
What else could cause a ghost image just to the top right of the mint mark if it's not a rpm Let me see if I can get some better photos
The listed one is not just a bit on the top right. This from VV clearly shows a fattening of the device across it's whole upper portion. And a ghostly image can be produced by a deteriorating die
