Some time back I had given up even trying to ID this. But, I kept at it and at least I can identify it. But, I still can't get the mint mark or other details.
Twins? After a bourbon I can almost make out TESA for Thessalonica on mine, maybe I'll have to try again tonight
Thanks to @seth77 I think I found my match. I will verify later. Have some stuff to do around the ranch today. Keep us posted.
