Past 4 2-letter .net domain sales:
FT.net $22,500 2007-08-08 Moniker/ T.R.A.F.F.I.C. (most comparable as it was the very last sale, plus the letters are close in quality to P and N)
KO.net $10,000 2007-06-06 Moniker/ T.R.A.F.F.I.C. (K is not a premium letter, and O is mainly good for Organization, more suitable for .org)
HM.net $12,250 2007-05-23 Moniker (both premium letters, but letter quality premium letters than P and N
JK.net $14,600 2007-05-15 Sedo (J and K are both non-premium letters, though “Just Kidding” is a saving grace for this. Still, do you want 5-figures for a name meaning “just kidding” or a name meaning “poker news” or “poker network”? Or “phone numbers” or “private network”)
Anyways, if I don’t sell it here for $20,000, it will sell at the next Traffic convention for that much or more, so want it or don’t want it, I don’t care. There’s only 676 2 letter .nets. Comparitively, there are 17,576 3-letter .coms that are now a minimum of about $4,200.
