What is a 1875 $20 Randolph National Bank, Randolph Worth?

There are only a few large sized notes known from the Randolph National Bank, Randolph
A note on this will likely be worth a decent value especially if the state is a highly collected one.
There are a handful of examples of the series 1875 $20 dollar bills from the Randolph National Bank, Randolph 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.
