I hunted the park today where I pulled around 30 modern silvers last summer and fall. Slim pickings at this point but did manage some clad and a 56 GW that I somehow missed in the past. This site has probably produced more silver coins than wheaties. Very strange but the strangeness continued today with the wafer thin silver? disc with a reeded edge. Weight is close to a dime. Possibly run over by a train. I need to test it I guess to know for sure.
