What is the value of an 1873 US 1 dollar bill?

The value of coins and bills can vary greatly depending on condition and stamping. 1873 stamped one dollar bills can be worth between $1,000 and several thousand dollars.

Note that there were no Federally-issued $1 bills with that date, but many private banks issued paper bills under Federal authority. For a more specific answer please determine the name of the issuing bank and post a new, separate question with that information.
