Do coin collectors examine their "paper" change like they do coins?

The thought crossed my mind today as I was researching some paper currency. For those who might suggest this is OT and I should take it on over to the paper forum, i'm interested in what coin collectors have to say about it

I didnt even know what a star note was until today. I guess I just make sure the cashier gives me the right change back, while I am picking through the change.

When I cashiered in a supermarket 58 odd years ago, I developed a speed system for checking currency. I didn't really have time to study each bill, so I checked the signatures. They were always in the same place on the note. If they were old, I set the bill aside.
edit: correct number of years ago.
Maybe I feel like a dope but looking at paper money in my daily rountine really didnt occur to me until a couple hours ago

edit: On further thought, it was 58 years ago.
I still have some of them including two $10 National Bank notes. Decades later I learned the first one of them was a low issue (First National Bank of Greenfield, Massachusetts without "& Trust Company" in the title). Perhaps a smarter move of mine was to save the crisp then new bills. The series 1928 red seal US Notes and series 1934 blue seal silver certificates were being replaced by the new series 1953. I couldn't afford very many but I saved some of the old and new types. A customer gave me two series 1953 notes in serial number sequential order. I almost made a big fuss over them being counterfeit. I knew check letters should advance from one note to another and these two had the same letter. The government had changed their method of numbering and never told me.

I check for the poker dollars and also for serial numbers that could be birth dates.
