how much does a domain like this cost ?

I have a domain that it starts with a digit and ends with "USD" word

NLLL.com

how much do you think i can sell it ?

depending on backlinks, pagerank, age and blacklists I think that offers up to middle XXXX USD wouldn't be unrealistic when you expose it for sale in the proper place and wait the neded time. However to be really sold in the best way, I think it will have to be developed in something, eg "dynamic list of all 7usd items selling and sold on ebay in the last 7 days"

any other idea ?
