Near a large CW US Camp with Artillery and Infantry, Dman and I had good luck in the last few years. Before Dman began hunting with me, I found some relics from that area as shown in the attached pics. Near a spring, I got a good signal under a large rock. It was a 1832 Mexican 8 Reales. I figure that one of the Yankees who fought in the Mexican War brought it back as a souvenir. Thanks for looking and Good Huntin'.
