The Redbook photo for the 51/81 overdate isn't particularly informative. Anyone familiar with these? Know how to spot an overdate vs. otherwise?
I would agree with the above opinions I think it is just a normal 1851 large cent but as stated it l9oks like a real nice example !!
George, you have a niceVF, 1851 lg.cent Perhaps one of the more experienced collectors, maybe able to help you, with the variety.
