Well I think it does for this coin... couldn't resist replacing the pf70 81s in my type set (the 81s was bought for other reasons lol) so for less then 1/2 list I couldn't resist her And Damn look at those polish lines on obverse lol
What you are seeing are not die polish lines. You have a starburst pattern of radial streaks. Error-ref says "cause uncertain".
It's not an easy attribution, certain years are just known for high relief, early surfaces. These half dollars are being heavily scrutinized.
I remember looking up information on a Canadian dime I got in change. The surface was mirror-like and I wondered if I snagged an impaired proof. That’s when I read up on the proof like condition. A circulation strike but a better finish than typical circulation coin surfaces. Since, I see this condition on foreign coinage, like the Singaporean coinage.
