Rick is one of the main men in this game,he has access to information and tools that we domainers dont have, but will say this, he sure knows how get the best out of his names and he seems to have a lot of respect in this game
Estimate for one was $2.0mil-$2.5min and it only sold for an eight of that at $250,000, although the monetization thing is something I really wish that I could get into and could become successful in.
estimates of the domain value are, quite often, higher than the actual amount at which the domain is sold at..overall is seems that he did quite well..
