What is the value of a US 1 dollar Federal Reserve Note?

So many $1 Federal Reserve notes have been printed in each series that almost all dates are only worth face value in circulated condition.

Bills from the 1963 series could retail for all of $1.25, and uncirculated $1 FRNs might retail for a couple of dollars. However those are selling prices on the open market. A dealer would pay wholesale prices, IF they were interested, but they probably have all the bills they want or need.
