ccTLD's are becoming more popular each day for businesses to have the local presence and respect for there country.
The popular cctlds (non-vanity ones) including: .CO.UK, .DE, .COM.AU, .EU all have premimum sales in the XXX,XXX region so in this case sex would easily go for upwards to 1 million.
Vanity ccTLD's like .CC and .TV could also see sales in the high XX,XXX.
The rest of them IMO anywhere from low X,XXX - low XX,XXX
