I hunted a new spot today and it was some really weird ground . There must be a spring under it. The ground was soaking wet . I left foot impressions in it . Other grounds I hunted today were hard as cement . I found about 20 modern coins using the Vaquero with stock coil and heavy on the discrimination . The coins I found were all deep , no surface finds . I think older coins probably sunk in the bog to far for the machine to reach , so I hunted quickly and cherry picked to see what the ground would give up . The very first coin I found was this Jefferson Memorial . The reverse has the St . Louis Arch on it so its not very old . I honestly thought i had a badly tarnished silver dollar at first .
