I got permission for an old, defunct bluegrass festival site. I did a quick 20 minute test hunt (too hot this afternoon). 7 coins, 3 from the early/mid 1960's. Nothing newer than 1993.
I suspect with a little effort, I should pull some silver!
Well, found lots of old clad and memorial cents. Missed silver by a few years on half a dozen coins. Close but no cigar. We have moved on th Lake of the Ozarks. Will keep on swinging. Hit me up if you are in the area!
