I may have the record over 800 coins, rings, seated, bust, on and on in less then an hour or so. . went detecting on Lake Erie after a major storm. The storm exposed some very large rock that were in a semicircle in a small carved out area of a cliff. All sand was missing on the beach exposing the slate with some sand existing behind these rocks. I waved my coil behind the rocks and got a half dollar signal on my Whites 6000DI series 2 and as I dug down for the coin I was finding silver dimes and more coins and I found the half dollar. I dug a load of coins and then I took a quarter that I found, called my dad from the pay phone, had him come down and bring a shovel. As I dug out the sand and threw it on the slate my dad scanned the sand with his detector and removed the coins, rings, crosses, silver, new money metal whats its and when it was all done we had over 800 coins. What happened, over the years the coins and items got trapped behind the rocks. It was the perfect storm that exposed the rocks. I still see the top of the rocks every now and then just the tops but the beach has about 3 feet on sand covering all but the tops of the rocks. Its was back in 1984 when this all happened. We found seated coins, bust coins, gold and silver rings, and so may wheats, new money, everything was trapped behind the rocks, plus the base of the cliff had a cut out in it and as far as I could reach I was dragging out coins. It may have been over an hour but it was a great day and me and my dad had a blast. I really miss him...
