I went to an old park today. Its been a while since I found any silver there but still get the occasional nickle. I found two coins today , both nickles . A 1940 and a 1904 . The 04 was maybe six inches deep and sounded good . I thumbed it up and it disc out at nickle , so that is what I was half way expecting . Iwas running the Vaquero with stock coil , minimum disc , sens slightly in the red , ground balanced neutral , and the threshold at 1 o'clock .
