1995 Civil War Unofficial First Day Cover Collection. The USPS released a collection of 20 different 32¢ stamps featuring a variety of Civil War participants and events on June 29, 1995 in Gettysburg, PA. A complete collection of FDCs cancelled in Gettysburg sells elsewhere for $85, but we've sourced an extra-special deal! Our set of covers was also cancelled that same day, but not at the official city of release. Instead, these "unofficial" collectible covers were cancelled at Beauvoir, the home of the Confederacy's president, Jefferson Davis in Biloxi, MS. Envelope artwork may vary from shown.
