Thanks for the responses! Love this site, first time posting.
Just seemed strange to me that there's no indentation/scratch mark/'plow' mark to show pushing onto the digit. I suppose a flat strike could do it but the 'D-bar' (for lack of a better term) isn't the same width of the '0' line and it appears straight, also, whatever hit it actually created another negative space (the inside of what would be a 'D').
I know you gentleman know what you're talking about but just curious, would anyone know of any other indicators on a cent like this that would identify the mint other then the mint mark itself?
