I found my first silver today! It is not a coin but only a small silver (925) Nike ring found at an abandonned baseball diamond near an elementary school. It was pretty bent up when I pulled it out from 3 inches but I managed to straighten it pretty well.
What do you mean 'at least'. I love finding silver rings, you should see my last one. Really bent out of shape and a big hole where the stone used to be, but it went in the 'treasure box' anyway. Beats a hor poker in the eye, or any cruddy clad!
