If you're looking for an endlessly interesting pasttime, consider a first day cover collection! A first day cover (FDC) isn't just any old envelope with a stamp as these collectibles are valued for both subject matter and postmarks. And the best part? Many are super affordable! The Bicentennial FDCs we're offering here are extra collectible as they each feature a commemorative medal honoring the occasion. In the 1970s, the U.S. Postal Service output hundreds of stamps for the event, so we'll choose the FDC issue based on our stock on hand. Designs will vary; you may receive different than shown.
