Hi all, I have a couple 2 Cents Washingtons here.. I'm not quite sure how to identify them (I already used the identification tool from 1847usa. All I know is that they don't look like an offset print and I can't find any watermarks (which doesn't mean there are none). They are all perforated 11. Is there any chance one of them could be a 461, 499, oder 546? I hope anybody could help me out and knows more about the different colours of these stamps. Thanks a lot!
