Its been a while since I have found silver quarters.Today there was a lot of work to do so I limited my search for about a hour and a half. I hunted in an area around a tree that I've searched with five other detectors.The CZ3D produced three faint two way signals they weren't crisp it sounded like can slaw.I thought about on passing these targets and avoid digging aluminum trash.After removing a plug on the first target it gave that crisp round tone,and down about seven was a 1959 silver Washington Quarter.Another foot from the first target same response from the CZ and again about six inches down a 1957 Washington Quarter.The last signal in the small triangle of targets was a early 60's penny. What I find interesting is the fact that I've been over this area.And yes I THE GREATEST COINHUNTER OF ALL TIMES had missed these targets.The group that I'll hunt a park with are only finding silver dimes.One of the other coin shooters and I were asking where are all the silver quarters? After these finds I think most of us don't realize a silver quarter will produce a target smaller than the wheat pennies that we find. Ron
