The "first spend" transaction with the new $10 note was made with the purchase of an item at the National Archives Shop.
The most obvious change to the redesigned U.S. currency is the addition of color. The new $10 note includes subtle shades of orange, yellow and red along with images of the Statue of Liberty's torch and the words "We the People" from the United States Constitution printed in red in the background to the right of the portrait.
What has changed in the new $10 design
A blank oval has been incorporated into the design to highlight the watermark's location. Small yellow 10s are printed on the face and back of the note. The oval borders surrounding the portrait on the face of the note and the vignette scene on the back have been removed from the design, with minor enhancements made to the engraving.
The U.S. government generally redesign its currency every seven to ten years.
The $100 note is also slated to be redesigned, but a timetable for its introduction is not yet set. The government has no plans to redesign the $5 note at this time, and the $1 and $2 notes will not be redesigned.
