Does any place still buy or sell CDs?

A dear friend passed recently and I’ve been helping her mother clean out her place. I’ve been taking the majority of her stuff to goodwill, but she kind of felt like the CD collection might be better appreciated if it was sold or donated to half price books or a record store. It’s all good 90’s alternative/indie stuff so I tend to agree with her mom that we can’t just take them to goodwill. I just have no idea if any place would even want them. Any suggestions would be most appreciated, thanks
