Value of 1957a series dollar bill with blue stamp value. SERIAL NUMBER C32808810A?
What you have is a silver certificate. They used to be redeemable for $1.00 in silver bullion, back in the days when the price of silver was controlled.
The 1957 series notes were the last issued before dollar bills were issued as Federal Reserve notes, so a lot were hoarded. In circulated condition your bill might be worth $1.50 to $2.00.
FWIW, a bill's serial number is almost always meaningless as a factor in the note's value. There are people who collect "interesting" numbers; e.g. 00000005 or 12344321, but the others are usually ignored.
