I would say about 20-30k for a reseller, just based on the name and fairly low search volume/few advertisers (Low for an industry defining one worder). However, it is currently ranked 2nd in google for the keyword mimes, right after wikipedia, so if you develop, and keep the rankings, then it might earn +10k a year from ads, more if you add in a directory.
With minimal development, it might be worth over 100k
