silverClad New Member United States 6 Posts	Posted 03/18/2021 8:20 pm Hello everyone. I am almost a total beginner who has a pile of coins which I am going through and been reading/learning/sorting/etc. over the past 3-4 months or so. This particular coin looks like it has a thin film of something over just a defined (non jagged) are4a of the reverse. Might this be an interesting coin I should keep or just throw back into the "circulation" pile? Thank you so much for your anticipated responses - including recommendations to just remove this posting. Looking forward to learning a lot more about coins. Report this Post to the Staff

Not worth trying to clean up, in my opinion. Worth 25 cents either way. to the CCF! Report this Post to the Staff
