Saw a Kennedy Accent Hair graded by NGC (looks to be older holder) and it lists the grade as PF 68 W. What does the "W" stand for in this situation? I don't recall ever seeing this before. Thanks!!!
This letter was used to indicate that a silver or nickel coin was entirely untoned, and its application was limited to certain modern series. NGC discontinued the use of this "W" designation in 2002.
I did not know that either... I have PCGS slabs though... and lots of raw ones I cherrypicked at coin and gun shows....A lot of dealers do not even check the AH variety...
Here is a link to a 2012 CoinTalk thread on this subject. There are photos of W and T slabs. https://www.cointalk.com/threads/the-ngc-t-w-designations-the-lost-designations.208532/
