Found my very first mercury dime today 1923 in great condition also found a musket ball I believe it to be buck and ball it's slightly bigger than a dime?
Nice recovery.......Mercs are about the prettiest silver coin ever made, to me. Just think about how many more are waiting for you to come along and dig them up!!
Congrats on the Merc it's a beauty !! Mercs are one of my favorite coins to find. I found a 1921D that gave me a nice return when I sold it but kinda wish I had kept it now. Good luck in your future hunts !!
