I think die deterioration and machine. Just take the B for instance. You can see the deterioration around the top of the B and the very shiny "sheering" of the metal around the bottom. You can see the distinctive splits in the letters on the Ike very easily. I don't think this is like the Ike at all. I want to say congrats on the Ike again. I love that coin!
this was a coin found in change, thats all. but I am going to my dads to pickup some silver roosevelt dimes, and more ikes, lots of roosevelt dimes, gramps had a lot of them, some silver Kennedy halfs, dad gone for the winter, lucky him lol
