A Florida voter sent in their absentee ballot with an extremely rare stamp, the 1918 Inverted Jenny. Two other stamps from the 30s and 40s were on the envelope as well. It looks like the stamps are sealed away with other voting ballots by law for 22 months.
Update: My skeptical friend David says this almost certainly has to be a hoax. "They used stamps.com or something to print these counterfeit images, knowing the votes would be locked up by law. What are even the mathematical chances that those three stamps are in the same place, and that the person who used them (all three) didn't know how valuable they were?" I am eagerly awaiting the follow-up to this in 22 months...I put an item in my calendar for September 5, 2008 reminding me to poke around for news at that time.
