I just saw a ngc graded 1840 $50 note in excellent condition sell for $200.00
A few cents for the paper it was printed on, or maybe a couple of bucks to buy it in a novelty shop. These "notes" aren't genuine. A billion dollars was 35 times more than the entire US budget in 1840.
A 1890 $1000 treasury note is not made of gold foil but rather paper printed with green ink. The note's value depends on its condition, rarity, and demand among collectors. Typically, the value of such a note can range from a few hundred dollars to a few thousand dollars.
Its an extremely rare note, potentially worth thousands of dollars at auction. If your are to sell it, don't go to ebay or a standard auction house. These sorts of items have a very specialised market. Best thing to do is to try and sell it to a numismatic dealer.
Probably nothing more than the historic value of the item. Unless you can locate the people or companies listed on the note, you are out of luck.
The value will depend on which 10 cent note it is and what condition it is in. It could range from a few dollars to a few thousand (but most likely something less than $25).
