The short answer to slabbing (PCGS or otherwise) this coin is 'no.'
While a tough date and mint, examples in this grade are usually seen unslabbed.
It would not be cost effective to slab.
A 2X2 or a plastic flip will protect it. And protect it you should.
But I see nothing to be gained from spending money on a coin that we all agree is a nice, original example.
A potential buyer in this grade would want it for an album most likely.
