Determining the true value of a Domain!!

[marketingS]

The best way is to ask an experienced domain broker who specializes in selling the type of domain you own. There is public historical sales data to help you compare domains to get a sense for median average values.

Ultimately, a domain name is worth whatever a buyer is willing to pay for it. Determining this price is an artform unto itself, with a myriad of contributing factors including length, language, trends and demographics.

I don't think that OP meant the cost of the domain!!
