This is my first post, so howdy everyone. I'm pretty new to coin collecting and I found this dime. Not sure what to make of it. I thought it was just PMD at first but the more I thought about it the more I thought it might be more. The "scratch" mark is just so perfectley circular and the way it cuts is really strange. Also the rim on the right side near the mark is much thinner than the one on the left. Not sure, that's why I'm coming to you folks to help! May be obvious to you, but to me it's up in the air.
Thanks in advance!
Edit: Forgot to mention. I think it;s obvious but the mark is in the lower right. Thanks!
