Another strange one, when you look at the U and N in UNUM, you can see a raised bit connecting the two letters together on the bottom of them. My apologies if this might be nothing. Thanks!
That is called a Die Chip. It also is a minor error with no value added. it does seem to be in an odd place,in my opinion.
Thanks again! I have about 5000 im going through over the holidays. Another obvious one I should have known. I'll try and look em up before posting lol.
