Advice required --> How do I value my websites' member database ??

Hi,

I have an opt-in database of sports fans from a previous, failed online venture.

How do I put a price on this db if I wish to sell it?

Quality of db is good
Depth of db is Ok - valid email adresses, gender, region, age
Size of db is small - 13,500 members

Any advice/guidance will be appreciated.

What type of sport is the database??
