United States Twenty - Dollar Bill
September 24, 1998: The Series 1996 $20 note was completely redesigned for the first time since 1929 to further deter counterfeiting; the picture of the White House
was changed to the north side view.
A larger, off-center portrait of Jackson was used on the front, and several anti-counterfeiting features were added, including color-shifting ink, microprinting, and a watermark.
The plastic strip now reads "USA 20" and glows green under a black light.[9] The bills were first printed in June 1998.[10]
