You could try the
PCGS site. You just need to enter your certification # and that should pull up what data there is on the note in question. There's not a lot on this site other than how to submit notes (coins) & info on the grades (& a lot of coin info). Set registries, news articles & prices are mostly coins (or bullion). It's very limited. I don't believe PCGS offers a population report like the PMG population registries & charts (which are far more useful) the way they're organized. I have only a couple PCGS notes in my safe (at the bank) & I have yet to entere their certification # to see what data gets revealed. I may be wrong but I suspect PCGS way behind PMG in that regard (their grading has improved recently but they generally don't certify the numbers PMG does).
Otherwise, if you have any other questions re: currency, your type of note, you should post this question on their forum at
Collector's Universe. The US-World
Currency forum can sometimes be quite useful too (though traffic varies) & its very USA-BEP centric/limited.
