ouch! Such a beautiful coin too! The seller gave me a partial as he hadn’t seen it when he listed it either. Probably going to end up being my Dansco type set coin.
Are you talking about the old cleaning (it would probably straight grade), or the tiny rim ding at about 8:30? Given the age, I'm convinced it would still straight grade with both. What's going on beneath the "6" in the date?
