I would like to know anything and everything about Separate Mint Marks. I found a 1955 D&S (though I haven't had it authenticated) Wheat back Penny. Obviously this is a very controversial "error" and I want to hear any opinions you might have. Also, the 'S' is horizontal, above and in between the 1 and 9 in 19. I've only heard of one other coin ever being authenticated but that it isn't considered a true error. I will post a picture but I don't have a very good camera, so it may take time to get one done.
