One or two numbers would probably command a premium, patterns would also. Both bills have three different digits so not a premium. I guess the "where's george" bill is a birthday note 2-22-2001 but with the stamp and condition it has likely lost any that it had.
I can't say any of your notes are particularly collectible (besides the birthday WG! note), unfortunately... Have you tried getting into star notes? Do you know of star notes? Maybe how about older notes some people collect? Those are most deffinately great places to start out if you were tuely interested in getting to know the ins and outs of US paper currency... Take $100 bucks to your bank, ask the teller to give you strap of $1's and look through them if you are truely interested in getting more into collecting. :smile
