Gents, I have seen a thread on another site regarding this coin and just came across one today. It looks like a 1991 Dime. Question is....grease struck? Thank you Rich
I want to say it was struck through a die cap. Your photo should be in better focus and more tightly cropped. This is one I took with my iPhone:
I have some pennies like your dime. I have a 1968 D penny and a 1973 D penny that look similar to your dime where the head sticks out a lot more than usual
