What is a 1875 $10 Union National Bank of Oakland Worth?

There are plenty of notes known from the Union National Bank of Oakland so a generic note on this bank will not be a great rarity.
There are a handful of examples of the series 1875 $10 dollar bills from the Union National Bank of Oakland 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.
