Old Phone Charger Cords-- What to do with them?

I have a ton, well I should say my boyfriend has a ton of old phone cords for cell phones. He must have 2 dozen of them, from all sorts of phones, some older models, some newew ones. He doesnt have the phones to go with them, just the cords.
I was going to see about listing them on ebay along with my other stuff, but there are SO many phone chargers on ebay that I really didn't think I'd get any good hits, unless I sold way cheap, then maybe.
Anyway, is there somewhere that buys them back or something? This is alot of phone charger cords here and I need to get rid of them, but hoping to find a way to make some chump change in the process... should I just ebay and see what happens. My next option is craigs list--- maybe I could go thru the wanted section to see if anyone is searching for the specific cords that I have.
