One of my first good finds was in my yard (1865 two cent) and that easily got me hooked. It gets better from there very fast !!
The coin you found is very cool, looks like it bounced around in a lawnmower blade !!
I didn't even think of a lawnmower. I was thinking someone was hammering on it or something lol! I'm on a military base so there is no telling what I'll find. So far I've found 4 M-1 casings and 1 .50cal casing from WWII.
