What is the value of a 1953 US 5 dollar bill with a blue seal?

The blue seal indicates that it's a silver certificate. Please see the question "What is the value of a 1953 US 5 dollar silver certificate?"for more information about its value.

Silver certificates were issued up till the early 1960s. The last ones were $1 bills printed as part of the 1957 series so they'll have that year followed by a small "B" to indicate when they were actually issued. At that time it was possible to exchange them for $1 in silver metal or coins, but when the price of silver skyrocketed the government stopped the practice. The bills are technically still legal tender at face value but are worth somewhat more to collectors.
