Burnside Civil War .54 Cal Cartridge, Rare, Dug, Gettysburg, Civil War. Condition is "Used". This is a rare dug Burnside .54 cal cartridge. The cartridge is intact. The cartridge was brass and shows discoloration from being in the ground over 100 years. You can see the unique hole in the base of the cartridge used for firing in the close up picture. I've always been interested in the Civil War so treasured this rare artifact. I purchased this in 1991 in Gettysburg, PA ...at The Shop Keeper on Taneytown Rd. It has been on display in my home ever since. The bullet portion has two small chips. Shipped with USPS First Class.
