It's easy to make a puzzle that's hard. "Guess the number in my head" is hard. It's not fun for the solver or reasonable. "Unscramble this text which was XORed with the Windows 3.1 solitaire EXE" is likewise. Good puzzles, even hard ones, should have some idea which way to approach them and should offer a method of attack other than brute force. |

The Wired piece has Sanborn saying the reserve should be "around $300,000."
It sounds like Sanborn really doesn't think it'll be solved before the auction date of 20 November (his 80th is on 14 November). If it does get solved due to this publicity bump, that's huge earnings foregone.
Perhaps he knows it is still an "unreasonable" challenge even with the 24 known letters.
