Unfortunately CD’s don’t seem to be worth much at this point in time. Just a couple of years ago, I stopped by a garage sale on a fluke and ended up buying just under 1200 CD’s for $150. I kept about 90 to fill in some blanks in my collection and then gave the rest to a buddy who took them to a huge Flea Market. He sold something like 125 of them out of about 1100! On his way home, he dropped the rest off at Saint Vincent’s thrift shop and he was nice enough to give me the receipt for my taxes.😁
All the best.
