I have had great results removing PVC with MS70 and a Qtip followed by a warm water rinse. Nice key date bro!
that is probably a good way to go to do spot removal but i don't know how thorough the grading companies are with pvc and while this and other items may not go through grading, it is a good idea to keep in mind that any coin with visible pvc probably has non-visible pvc that may show up with special lighting and/or different lighting angles.
my point is that if one is going to take the time and effort to do spot removal, it is probably a good idea to just do the whole coin to be safe and with acetone, there is little risk to the coin. it is possible we may overlook other spots/accumulations. it is possible any chemical can remove good gunk from the surfaces leaving something desirable underneath. i'm pretty sure i've had that happen a couple times.
I have my own, un-approved, grading system. This one rates "Would fit right in with my other Whitman folder Walkers". That's about as deep as my system goes................

Not my series, but AU-50.
XF40 with a weak strike in the center.
xf-40 with pvc
XF to me.

The reverse wing? I suppose I should give it an acetone bath...

Green spots on obverse look a little like pvc too.
XF45, looks like it was cleaned some time ago, but probably market acceptable.
VF 35 shot at XF 40.
definitely not higher than that.

I would stick with acetone on this coin. Use of MS70 will remove what little “skin” the coin has reacquired over the years.

XF details on both coins, there's a reason why a 1938-D like that is raw...
Cleaned XF-40
Yes, to the question. To PCGS, for the answer.
I’d think 45 ish
