While I was clearing out some boxes I came across a few Dragonball Z DVDs. My son watched them once or twice before getting bored and going onto something. That was over ten years ago before graduated from high school. Any idea what they might be worth, if anything?

They're worth if anything. Donate them to your local public library or something similar.

If you have a Goodwill or Salvation Army store in your area, you can donate them there and I'm sure they'll find happy new owners.

Well, that's all true for the most part, unless you have something like the Dragon Boxes which are (I think) still worth some money (though it is unlikely that you have them if you just got whatever the cheapest option was at the time for your kids). But yeah the "normal" DVD releases, most of which are flawed in some key way, aren't worth much. Funimation isn't shy about pumping out new "improved" (but still lacking in some key way) versions. But they only had the license to sell the Dragon Box version for a limited time.
