Well today is the third day with my Excalibur II. Todays finds are: 13 dimes, 7 quarters, 6 Nichols, 14 pennies, 1 silver ring states USA .7, whatever that means, 1 cell phone, and one platinum ring, belonging to a guy I met at the beach grandmother. He lost the ring on the beach a weak ago, pointed me in the right area and I found it 3 min later. It made me feel real good being able to get it back to him. It was the only thing he has of his grandmother. Now I need to figure out how to clean some of these coins
