Okay, I just had an interesting idea for the serial #'s on bills (though it's probably been done already. But who knows, maybe I just came up with a new collectible fad. 
)
If you look at the key pad on a phone, most of the numbers also have letter equivalents. What if you converted the serial # to letters?
Here's an obviously made up example:
L 6 6 5 2 8 8 4 4 S
L mm j a t t g g S
L n n k b u u h h S
L o o l c v v i i S
(LookatthiS)
2=abc 3=def 4=ghi 5=jkl 6=mno 7=pqrs 8=tuv 9=wxyz
Crazy idea, or what?
