Well here's the oldest half dollar in my collection and just like most of my other early American coins I got this from my grandfather. And the story behind this one is he found it in an building on the edge of his property
I think I see a trace of a 4 to the left of the final four? I'm going with O-110, R.2 as the Overton, though I could be wrong...
This is super cool coin. Not only is it a nice coin but you got it from your Grandfather! My Grandfather got me started collecting coins and Tokens. Unfortunately I was ripped off for everything I got from him but the memories still hold a special place in my heart!
