What is a 1902 $20 Farmers and Merchants National Bank of Nampa Worth?

There are several large sized notes known from the Farmers and Merchants National Bank of Nampa so notes from this bank aren't particularly valuable.
There are a handful of examples of the series 1902 $20 dollar bills from the Farmers and Merchants National Bank of Nampa known to exist.
Even notes from common banks can be worth a decent amount if they are in great condition or they are serial number 1 notes.
If you have any doubts please contact me with a picture of the note. I love to see new national currency.
