Authentic Civil War Bullet Recovered At Miller’s Corn Field Antietam Recovered By Dean Thomas. A Union 3 ring bullet from our collection. We have several and we will pick the best one for you. Some are fired some dropped. One side says “corn field” some have Dean Thomas’ numbers. Legendary Relic Hunter, Author, and historian Dean Thomas had permission to hunt the part of the bloody corn field that was private property (now it is owned by the National Park) so there will never be any more relics coming from this area. Miller’s Corn Field is considered by some historians to be the bloodiest single spot from the bloodiest single day in the Civil War. Very limited supply. Comes With Museum COA.
