This is where the auction format comes into its own, a market value can be established for such domains.
This is why I have put such low minimum offers on them because I realise that at the auction stage they will rise to what they are worth, whatever that may be!
As I say, I may be stupid, but I am not that stupid! I would rather sell for a decent $xx,xxx now than wait 4 years or longer for someone to come along and value them at $xxx,xxx!
