I got this coin and I am not sure what the series: 32PR means, as well as the Coin: 26. Thanks for the info.
PR is an abbreviation for Proof. I would think that "series 32" means they are referring to the Roosevelt Dime series, so in my thinking, it is saying that this coin is a Roosevelt Proof Dime.
PCGS has a numbering/classification system that they use in-house and series 32PR is for proof Roosevelt dimes while coin 26 means it is the 26th coin in that series. That's it.
