A gorgeous example of this popular type that is less and less frequently seen in high grade. The 1966 $100 red seal is currently the most valuable of the red seal types as well as the last of this type of note. Currency with a red treasury seal and red serial numbers is one of the most curious types of money to be found in circulation. These notes are printed with the words "United States Note" in the scroll work at the top center of the note. These notes, issued at a time when money was redeemable for gold or silver, were backed only by the credit of the United States Government. They were issued in $1, $2, $5 and $100 denominations.
