Clinton, Mississippi is west of Jackson just off I 20.
Use to know a couple of guys in Vicksburg that were Civil War relic hunters. I went metal detecting with them a few times, and amazing how much is still in the ground around there. They took me to a place called Old Warrenton just south of Vicksburg which was a Union camp ground. They had found over 200 coins in the area, with most being half dimes.
