In general - FRN is just a way to classify the type of bill. currently allof our bills that we use are FRNs. In the past there have been different types United States Note, National Bank Note, Silver Certificate, Gold Certificate and I'm sure others. The different types have to do with how the financial system was set up when the note was issued.
I don't know if silver certs or gold certs were technically a FRN, but collectors will usually refer to those as gold or Silver Certs, not as an FRN.
