PCGS and NGC professional grading services take all coin surface and strike or die issues into consideration. A grade is based on the evidence and the criteria of the item or case as presented.
In fact, it does not even mean that the same coin could be submitted again in "raw" condition and receive the same grade from either grading service. I have sent several outstanding coins to CAC that were ignored and rejected. I was shocked and disappointed but they are the accredited experts we defer to as are PCGS and NGC the same. We all trust the expert grading services to authenticate our coins and to grade them subjectively. The only thing certain about grading is that the coin is authentic and that buyers and sellers have an arbiter in PCGS or NGC to decide the grade of the coin.
Too many additional variables exist in these COVID times. Choose carefully and choose wisely with eyes wide open.
