I haven't gotten one correct yet, though I feel my grades shouldn't have been off. I would normally say a 45 the luster is in the periphery's and hidden against the devices. Yet I think they gave it a 53.
This is also a guess the luster thread. The images I'm posting don't do a great job of showing luster.
I would call it 45 to 50. It appears to be the Large O so not 108. O-122 which is one of--if not the--most common die marriages for the year.
I will guess 53. What is going on with the reverse from the wing, through the beak, to the S of pluribus?
