I need some help with this coin I have. 6 or 7 years ago I found in a roll of new Delaware Quarters never thought anything about it. Then I Read about this Error called an improperly Annealed coin sometimes called Black Beauties. I found one on
ebay and my coin looks just like that one But how can you tell. Any help would be nice and what would this coin be worth ? Thank you all very much Maxwell 41. :-) sorry can't seem to put up any photos.
