I don't like the look of that coin at all... just something about the appearance that appears to be "off" (might just be the pics). I'd like to see a better photo of the reverse; it's hard to tell if that "dot" is even a mintmark.
I can't identify by the pictures, but here are the potential VAMs that it should be. Nice coin. http://www.vamworld.com/1878-S+VAM-9 http://www.vamworld.com/1878-S+VAM-21 http://www.vamworld.com/1878-S+VAM-53 http://www.vamworld.com/1878-S+VAM-79 It should be one of these VAMs. Good luck.
i agree. the denticleslook odd, especially on the reverse. have you weighed the coin or put a magnet to it?
i tested it and it also weighs correct. i will try to get a better picture i noticed it also looks like it is off center slightly the space behind the denticles is wider on the right side than the left . Again thanks for the help
