Just back from anacs. It is a strikethrough of a laminated denticles area that flaked off of a previously struck coin...
Im wondering if that is what mine is too... btw... looked through a 30/60X loupe and there is wood debris all over the reverse of my one Morgan. Under 60X you can see the fibers of the wood grain. Sent from my SM-G935P using Tapatalk
I'm pretty sure that's what yours is too. Just much more cool. You stole yours for the price you paid. I'm super jealous, you are a suck suck suckerface! I'll take yours to long beach in about 6 weeks and get Fred's in-hand opinion if you want. I'm probably gonna get a table again
