My dealer gives 1957 silver certificates in tough shape like yours as change. Your note is in poor shape and just worth face. These are also very common and generally worth little even in uncirculated. A few months ago I helped my brothers neighbor with selling off her dads coin/currency collection. She had $147 in notes in comparable shape, the dealer exchanged them for $147 in modern currency.
As to what your note is, prior to federal reserve notes (green seal), US notes were tied to either an obligation of the US Government (red seals), worth the amount in silver (blue seals) what you have or worth their value in gold (yellow seal), there were others like brown (notes issued in Hawaii during WW2) or national bank notes (issued by national banks). Prior to 1966 you could have exchanged the silver certificates for actual $1 silver coin or when those were done $1 in silver bullion. Today your note is still worth $1 but would only be exchanged for a federal reserve note (modern green seal)
Here is an example of 1 of mine.
