First Day Issue USPS

[steve B]

While regular first day coves don't get much, these would.
Whoever did them went to the extra effort to add stamps that went along with certain schools, and got the signed. That's sort of on another level.

Being the odd collector I am, I also collect first day covers signed at the first day ceremony, usually by the designer or some local dignitary with some connection to the subject. Or more commonly the postmaster of the place the ceremony was held. Not worth much, I can often find them in cheap lots or the dollar box.
Touger and less valued still are first day covers that got ruined. Damaged in the mail, return to sender, Postage due?! The more messed up the less others like them and the more I like them. (unless they're incredibly messed up, then everyone wants them)
