Sorry. I've been thinking. Lol
Strike through and Greaser
sounds great possibilities. But?
If it's a strike through wouldn't it (maybe) show some kind of ridge at the collar line? If it is a strike thru would there be a ridge?
If it's a Greaser
wouldn't it (maybe) follow the beard line? Approximately at Green line? Sorry for the wiggly green and red lines. Fat finger and caffeine.
The arrows pointing at bottom of beard and Adam's apple. Just in case you didn't notice.
I hesitate to throw this wild guess out but. Could it be something like Greg's/CoinHi's 2020P Roosevelt. Bi-level (stepped) die crack?
