They are of course different domain names but as a guide I think they show to an extent an 'active' market in the sense that these are very similar and have been sold. Perhaps valuing them more accurately than other names on here which we speculate on.
Ultimately, however, an item can only have a proven value when it is sold and creates a market for itself - that's why it's a guessing game!
These names could be used widely and are of course dot coms. Am I wrong to think they are far more valuable than reg fee?!
