Dont know if thats true, but last week I found a gold bracelet(womans) got a silver ring today(womans) You guys and (women) been detecting a while should know the answer. Anyway Hunted three spots today with my the Ace 250 and Humpty Dumpty(ATPro). I found 3 wheats 5 clad dimes, A Silver ring missing the stone, Alabama luxury tax token(maybe from the 1940's made of aluminum and beat up) and a few pounds of scrap copper and brass. I sold my copper and brass findings for 8 months of detecting a couple weeks ago and wound up with a considerable amount of money. I havnt sold all my lead that I have found , but I think its around 50 pounds . So from junk to jewels I love it .
