I know records and record players are considered old school but people still pay for them them?

My mom has a bunch of records, Chaka Kahn Eric Gable Prince the list
goes on. She found this ad in the paper from a person who is
interested in buying records she just wants to know how much they are
worth before she calls this guy.

SHe doesnt want to get cheated I guess, so how much does some store
pay for records, or does it depend on the artist.
Excuse the typo "double word" I was in a rush typing this
