As a brandable domain I think it's just OK.
At present, it's not worth much, I can't see many people prepared to pay low $XX for it.
I think you have two options for selling it:
1) You could hold it for 10 years, hoping that all 5 letter .com's have been registered by then and it's worth a couple of thousand dollars (like what a 4 letter CVCV.com is worth at present). It has 4 premium letters, with a two D's and E's.
2) You try and sell it now. I notice that dedey.us has been registered, they might be interested. I also notice that it's a (very) rare last name. Find a few people with the same last name and try and sell it to them.
Your best bet is to probably develop it. What should you develop it into? Either a high paying adsense cpc topic website, or some topic that you're interested in. Get some traffic and you may be able to sell it for more than $XX.
Good luck with it.
