Left early this morning and hunted about 3 hours. Found 43 quarters, 19 dimes, 11 nickles, 47 pennies, 5 silver rings with 2 having small diamonds but don't know if they are real and a 14k teeth grille. Tested it with 10k, 14k and 18k acid, the first two didn't phase it, the 18k dissolved it. Thanks for looking. HH
