I found this coin with a extra letter O on george washington face http://s1232.photobucket.com/albums/ff378/loulou1066/?action=view¤t=IMG_1650.jpg http://s1232.photobucket.com/albums/ff378/loulou1066/?action=view¤t=IMG_1647.jpg http://s1232.photobucket.com/albums/ff378/loulou1066/?action=view¤t=IMG_1646.jpg
what is the different of a dent and a real O? If you can tell me then i can tell you if its a dent or not,
You might be onto something With Extra O http://minterrornews.com or It might have been About.com error coin forum. Im pretty sure it was one of these two places that I saw an article on Second O GWD. Good luck in your search. Hope this helps out. :hail:
The entire portrait is covered in dings and scratches. I don't see anything to make that ding special.
For an extra letter, look for the elevated surfaces that would be created by the engraving in a die. This looks like every part goes inward ? So it's likely the coin was struck with something ? Either a metal chip when the coin was stamped or later by something. die chip or post mint damage is my thought
