You can tell it isn't counterfeit from a dark picture? For the record, I rather doubt it is which is why I'd like to see the OP clean it and post it to close the loop because even if it was a fake, that would still be pretty cool (maybe even cooler).
Sorry it took so long to post again lol but it was a very crudded up think it sat in cow s!!! For 50 years lol it's a 1943 quarter. I've never dug a silver that was that hard to clean up. So now I know that silver can resemble a corroded copper. Thanks for all your posts.
