As I take a dollar bill out of my wallet, I see the serial number is D 75655246 B nearby there is a "4", and to the left of the 4 is an F2. It's a 1981 note. It would be interesting if someone who knows the structure of serial numbers would comment on it. In particular, how much information do you have to include to insure the number is unique? Are the D and B necessary? The 4? The F2? The date on the bill? Can we be sure that the 8 digit numbers won't grow to 9 someday? Will the numbers ever repeat as bills are recycled? Mark
