Could someone let me know where I can find a description of this type and what to look for? Thanks in advance!
There's a link in this forum. Use the search feature and it'll be there. It was a good one too. Basically your looking for the eagles right wing (your left) on the bottom it has 3 tips instead of 4 like the normal Mint ones to. The 3 wing ones are a proof reverse die. (see I can learn)
