Found this in a roll of halves. Fingerprints don't look near as bad as they do in this scan. Worth anything? Should I seal it and save it for 25 years?
eBay it as a "RARE circulated proof" I'll bet you'd be surprised at what it brings! Otherwise keep it as one of the interesting coins that you found in a roll. I have a couple of rolls of "interesting" things that I've pulled from Kennedy rolls. They aren't worth a huge premium, but they are interesting enough to keep.
