What to do with a large collection

I’ve tried giving away Classical CDs as I burned them to a server.  As per the OP, even libraries and charities aren’t interested.  My heirs will be stuck with a few thousand.

I try to sell mine but the job asked for doing it was too much for me and at a ridiculously low price...

Those who are not streaming or listening files buy only vinyls...

Digital is immaterial, no fetichism here, a vinyl  album is a cult object and keep some value ...Even when it is on a wall and not playing ...

I dump all my remaining cd in bulk in a ONG for the poor ...many thousands ...😊

I now live with many thousands lossless files...

I owned an estate sale company for 27 years and LP records where a hot item at our sales. There where a dozen or so regular buyers that would swoop in and buy most on the first day. I would price most of them at $2.00, up to $4.00 or $5.00, then would go 1/2 price on Sunday, however most good ones would go on the first day. CD's $3.00 ea. where not as much in demand.

Lots of good advice here. If you don’t want to give it away, then catalog your collection. Create a photo album (cover art) and post it on Audiogon and USAM for sale. I know this is time consuming but there are lot of folks out there that still spins CD’s. BTW, I gave my previous collection of 1500 plus CD’s to Goodwill after ripping. 

Fittingly, I sold my LP collection and turntable to an antique store.  They were also in the business of selling LPs in store and on eBay.  I still have my CD collection as they weren't very interested, although they do sell used CDs.
