What is the highest grade of UNC note with pin holes? I have a 1899 $1 PCGS graded 63 with a comment of pin holes.
You will usually see comments like this when there is a major issue, but If i understand your question correctly, your asking what is the highest Grade of a not with pinholes or staples, i have seen up to a 66, but With that said chances of getting a PPQ or EPQ grade are slim to none.
Comments, are usually placed on the back to indicate if theres a problem Sometimes you have to look very hard as some can be hidden pretty Well.
First you have to know that the italics grade number means APPARENT because not every collector knows this, and second, you have to hope an unscrupulous seller hasn’t removed the notations from the back of the holder. PCGS uses an exposed (unprotected) paper label.
Simple, and what all collectors should do, you can actually look up notes With there serial numbers through the TPG, questions or not.
