a 3 cent piece at a good foot plus with an Eagle Spectrum and a hot head coil on it. The ground was soaking wet mud, I was going squishy squish walking in it. Up in Illinois, on great lakes naval training center to be exact, in the picnic area down by the lake. This was in late june that this happened. June 22, 1994 to be exact. Yes I keep records of all my major finds. It rang as a good solid tone that didn't 'chop' like pulltabs do, but was kind of iffy on the vdi, after several passes with the coil the tone was very steady in the silver range, and as I dug, didn't change much, it'd bounce between penny / dime with occasional nickel but stayed in penny dime range. The one thing I never liked about the hot head was that the depth readings were crap. I questioned digging this thing a few times on the way down, saying wtf, I don't have it yet? But the signal was so steady and tight, I could tell it was not a pulltab or beercan shrapnel, but didn't know what it was, but felt it was 'something' good. Pulled up a mud blob, rubbed a bit off the edge seen silver threw it in my bag. When I got it home and soaked and gently brushed it clean and seen the III on the back, then I knew I found a once in a lifetime thing, but to this day, have no idea how it got there. Coin was from the mid 1800's and they were NOT popular at all with the people... so it's not like theyd be in major circulation, and the base was not really built until around 1911.
Zion settlers perhaps? Pony Express route? Jr got into daddy's coin collection? Your guess is as good as mine.
