I was reading a thread about a guy finding a rosy in his yard. I thought about never finding silver in my new yard but then remembered a really promising high tone I got last year. About 6" down I hit a big r3-4". My TRX said it was straight below it. I dug all the way around it but it wasn't under but in it. Too big of a root to cut and hurt the tree for a coin. I'll always wonder what it is.
