Nope, it is a United States Note with a red seal(all red seals are US Notes)

means it wasn't a Federal Reserve Note it was a US Note, both were legal tender but made in different places run by different institutions.
From Wikipedia:

Both United States Notes and Federal Reserve Notes are parts of the national currency of the United States and both are legal tender. Both have been used in circulation as money in the same way. However, the issuing authority for them came from different statutes.[17] United States Notes were created as fiat currency, in that the government has never categorically guaranteed to redeem them for precious metal - even though at times, such as after the specie resumption of 1879, federal officials were authorized to do so if requested. The difference between a United States Note and a Federal Reserve Note is that a United States Note represented a "bill of credit" where the currency was transferred into circulation free of interest. Federal Reserve Notes are based on debt purchased by the Federal Reserve, and thus generate seigniorage for the Federal Reserve System which serves as a lending intermediary between the Treasury and the public.
