What is the value of a 1976 2 dollar bill with mismatched characters?

Answer 1

It's not clear what's meant by "mismatched characters". If that phrase means that the two serial numbers are different, the error can be worth anywhere from $100 to $200 depending on the bill's condition.

Serial numbers are printed by a pair counters for each bill. The counters work a bit like an old-fashioned date stamp or the mechanical odometers found in older cars. The counters are supposed to be linked but occasionally one will get stuck, causing the two serial numbers to get out of sync.
