i think not so much, it's many other possible domain names for registrars. generaly not so many people know what TLD mean, i mean that for many internet users it'll be 6 random sign domain name. In my opinion $2k-$5k but if you make them some portal price will grow up immadietly.
I think you've got something good there. There definitely are alot of European TLDs out there. The name would be good for a directory of TLDs, a registrar, domain listing service, etc.
I'd say low to mid $xxxx maybe more to an end-user.
