If you have a bunch of old CDs or DVDs in the attic along with some other retro tech , why not sell them so they can be enjoyed by others? You never know, some might be worth something. The truth is, only rare or highly sought-after discs have a chance of earning you some serious cash on the resale market. Most are probably worth up to only a few bucks each, but a few simple checks can help you find out whether your old discs are worth anything.

For maximum resale value, the discs should also be in tip-top condition, without scratches on both the box and the disc. The insert should also be in pristine condition, free of creases and tears. Even better, the disc will still be in its original, unopened packaging. If you're confident your disc is valuable, it's time to find a buyer.

Online marketplaces like Discogs and eBay can help you reach collectors directly.…
