What is a 2.00 bill with the serial number A10238869A worth that is in mint crisp cond?
As you've seen in posts from many other people, a bill's serial number doesn't help to ID it. It's a bit like trying to ID the make of a car based on its color.
If the bill has a green seal and a date of 1976 or later, it's worth no more than $3 retail; a dealer will pay face value only.
If the bill is earlier than that please post a new question giving the bill's seal color, date and what letter, if any, appears next to the date.
