Were it not for the coin being a 1921, I'd say no. You might get lucky, and $25 seems worth gambling to take a shot.
The cert# seems fairly recent. If they didn't give it PL the first time I doubt they would on a resubmit. But who knows.
It's hard to tell from those pictures. I like the contrast between the fields and the devices, but I think it falls just short of PL, not enough mirror.
I think it is very close but I think it isn't there. I think the obverse especially isn't strong enough.
