I was wondering if anyone is good with programming or maybe there is a site out there already that does this. I want to be able to put my serial # and series into a search to see if anyone has a sequential number to it. Any positive ideas are welcome.
Track & Price Currency has a census with all "known" serial numbers. But the term "known" does not account for most raw notes on the market. You can also try Where's George, as I believe they have a S/N search. Just search one number above yours, and one number below.
