Interesting serial #s are ladders (going up or down in the individual #s), low #s (4 or 5 leading zeros), radars (like the word radar -- reads the same from left to right and vice versa), and year notes (last 4 digits are a year).
It really doesn't add any extra value, unless you can find the right collector that is willing to pay a premium for them. I'm not one of them. I don't see why it should add any extra value (maybe a few dollars at most), since all serial #s are unique for that series and branch.
