What is value of a blue seal 5 dollar bill dated 2006?

Answer 1

The last blue-seal $5 bills were dated 1953. A blue seal indicates a bill is a silver certificate. A 2006 bill will have a green seal and be a Federal Reserve Note.

There were 2 types of $5 bill issued as part of the 2006 series, however. One uses the old green and black design, while the newer one is gray and purple. Both carry the same date because they were printed under the same Secretary of the Treasury, who took office in 2006. Neither one is special or valuable, just worth $5.
