I found a few possible mistakes on about 3 coins today but I'm pretty sure most of it is machine doubling and damage. I'm still not sure though. I have been studying the different types of errors but am still learning. I added them all to the one post so I'm not hogging the forum with posts. Anyone have any opinions on these? TIA! This 1992 D Roosevelt dime appears to have doubled die date and mint mark. It is one of those that is hard to tell the difference in whether it is a doubled die or one of the worthless ones like machine doubling or from a worn die. The second D is pretty clear regardless. This 1977 Quarter has what appears to be a doubled die neck at the bottom above the 7's in the date. This one I'm not sure about either. I found this 1990 Quarter that looks like a possible doubled die on the forehead but it most likely is damage.
