Beware of fakes. Not saying these are, but warning potential buyers. If these are from buying AMD graphics cards, then you might be required to present a picture or scanned image of the actual code on the packaging to verify. A while ago, quite a few fakes of these codes were made so AMD has been cracking down.
Again though, I don't know about these (and the buyer could still be trustworthy, he might have gotten duped too). Good luck selling.
Actually steam leaked their entire code database, so they have to verify you actually have the cd key coupon.
