Hello RD, I think that looks like the planchet was 1st marked with that impression, then the die struck the planchet making this a coin.I say this because it appears that the "marks" are under the die strike.NICE COIN, remember this is only my opinion. BE WELL, MORGANS DAD...
PS: IT ALSO APPEARS THAT ON 4 SPOTS AROUND THE COINS PERIMETER, AT SOME TIME THERE WAS A HEAT SOURCE APPLIED TO THE COIN.GIVING A BURNT EFFECT..
