, do not know about the twenty. I recently sold a 2003 A five dollar bill with no treasury seal for $70 on ebay.
$20 Dollars.
nothing
Up to a whole $2. The Treasury is still making series 2003 bills.
On the 5 dollar bill: Redeemable in gold on demand at the united states treasury or in gold or lawful money at any federal reserve bank. 1928 series A A.W. Mellon secretary of the treasury
If you have four of them, then the set is worth $80.
To set the value of the dollar
In circulated condition, it has little or no added value. A nice crisp uncirculated one is worth about $50.00
Despite their age, $20 bills from the 1950 series rarely sell for more than a dollar or two above face value.
Not enough information. What date? What condition? Please post a new question.
1848. Silver. Twenty. Dollar. Coin
The National Treasury, I believe.
