Andrew Jackson has appeared on the $20 bill since the series of 1928. The placement of Jackson on the $20 bill is considered ironic; as president, he vehemently opposed both the National Bank and use of paper money. After the president of the Second Bank of the United States, Nicholas Biddle, defied Jackson and requested the renewal of the charter of the Second Bank in an election year, Jackson responded by making it a goal of his administration to destroy the National Bank.^[3][4] Jackson prevailed over Biddle, and the absence of the Second Bank contributed to a real estate bubble in the mid-1830s. The bubble collapsed in the Panic of 1837, leading to a deep depression.^[5]

Given Jackson's opposition to the concept of a National Bank, his presence on the $20 bill was controversial from the start. When pressed to reveal why the various images were chosen for the new bills, Treasury officials denied there was any political motivation. Instead, they insisted that the images were based only on their relative familiarity to the public. An article in the June 30, 1929 issue of the New York Times, stated "The Treasury Department maintains stoutly that the men chosen for small bills, which are naturally the ones in most demand, were so placed because their faces were most familiar to the majority of people."^[6] It is also true that 1928 coincides with the 100th anniversary of Jackson's election as president, but no evidence has surfaced that would suggest that this was a factor in the decision. According to more recent inquiries of the U.S. Treasury: "Treasury Department records do not reveal the reason that portraits of these particular statesmen were chosen in preference to those of other persons of equal importance and prominence."^[7]

• 1914: Began as a large-sized note, a portrait of Grover Cleveland on the face, and, on the back, a steam locomotive and an automobile approaching from the left, and a steamship approaching from the right.
• 1918 (1918): A federal reserve banknote with Grover Cleveland on the front, and a back design similar to the 1914 Federal Reserve Note.
• 1928: Switched to a small-sized note with a portrait of Andrew Jackson on the face and the south view of the White House on the reverse. The banknote is redeemable in gold or silver (at the bearer's discretion) at any Federal Reserve Bank.
• 1933: With the U.S. having abandoned the gold standard, the bill is no longer redeemable in gold, but rather in "lawful money", meaning silver.
• 1942: A special emergency series, with brown serial numbers and "HAWAII" overprinted on both the front and the back, is issued. These notes were designed to circulate on the Hawaiian islands and could be rendered worthless in the event of a Japanese invasion.
• 1948: The White House rendering on the reverse of the bill was updated to reflect renovations to the building itself, including the addition of the Truman Balcony, as well as the passage of time. Most notably, the trees are larger. The change occurred during production of Series 1934C.
• 1950: Design elements such as the treasury and Federal Reserve seals are reduced in size and repositioned subtly, presumably for aesthetic reasons.
• 1963: "Will Pay To The Bearer On Demand" is removed from the front of the bill and the legal tender designation is shortened to "This note is legal tender for all debts, public and private" (eliminating "and is redeemable in lawful money at the United States Treasury, or at any Federal Reserve Bank.") Also, "In God We Trust" is added above the White House on the reverse. These two acts (one taking U.S. currency off the silver backing, and the other authorizing the national motto) are coincidental, even if their combined result is implemented in one redesign. Also, several design elements are rearranged, less perceptibly than the changes in 1950, mostly to make room for the slightly rearranged obligations.
• 1969: The new treasury seal appears on all denominations, including the $20.
• 1977 (1977): A new type of serial-number press results in a slightly different font. The old presses are gradually retired, and old-style serial numbers appear as late as 1981 for this denomination.
• 1992 (1992): For Series 1990, new anti-counterfeiting features are added: microprinting around the portrait, and a plastic strip embedded in the paper. Production of Series 1990 bills began in April 1992.^[8]
• 1994: The first $20 notes produced at the Western Currency Facility in Fort Worth, Texas are printed in January 1994, late during production of Series 1990.
• 1998: The Series 1996 $20 note was completely redesigned for the first time since 1929 to further deter counterfeiting; A larger, off-center portrait of Jackson was used and the view of the White House on the reverse of the bill was changed from the south portico to the north. Several new 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] Production of Series 1996 $20 notes began in June,1998.^[10]
• 2003:^[11] The redesigned Series 2004 20 dollar note is released with light background shading in green and yellow, and no oval around Andrew Jackson's portrait (background images of eagles, etc. were also added to the obverse); the reverse features the same view of the White House, but without an oval around it. Ninety faint "20"s are scattered on the back in yellow as a "EURion constellation" to prevent photocopying. Production of Series 2004 $20 notes began in April, 2003.^[12]

Series dates

Trump administration

While campaigning for president, Donald Trump responded to the announcement that Tubman would replace Jackson on the twenty-dollar bill. The day following the announcement Trump called Tubman "fantastic", but stated that he would oppose replacing Jackson with Tubman, calling the replacement "pure political correctness", and suggested that Tubman could perhaps be put on another denomination instead.^[21]

On August 31, 2017, Treasury Secretary Steven Mnuchin said that he would not commit to putting Tubman on the twenty-dollar bill, explaining "People have been on the bills for a long period of time. This is something we'll consider; right now we have a lot more important issues to focus on."^[22] According to a Bureau of Engraving and Printing (BEP) spokesperson, the next redesigned bill will be the ten-dollar bill, not set to be released into circulation until at least 2026.^[23][24]

In May 2019, Mnuchin stated that no new imagery for the new 2028 $20 bill would be unveiled until 2026. He also reaffirmed that the new $20 bill would not be moved up ahead of the new $10 or $50 bills due to counterfeiting security concerns regarding the $10 and $50. Mnuchin would not say whether he supported keeping Tubman on the redesigned $20. He said that the decision will be left to whoever is Treasury secretary in 2026.^[25] Democratic members of the House of Representatives asked Mnuchin to provide more specific reasons for the design release delay. (The production date of new $20, 2028, was unchanged from timeline announced in 2016 by the Obama administration)^[26] The Director of the BEP, Len Olijar, released a statement saying that the "BEP was never going to unveil a note design in 2020" and that the illustration used by the New York Times was not a new $20 note.^[27] Later in June, the Treasury Department's acting inspector general, Rich Delmar, sent a letter to Senate Majority Leader Chuck Schumer stating that his office would investigate the issue.^[28]

In June 2020, the Office of Inspector General released a report detailing the results of its investigation, which concluded that the $20 note's position in the redesign sequence had not changed, that the earlier announcement of the 2020 date by the Obama administration "was made outside of the note development governance structure and without the recommendation of the ACD" (referring to the Advanced Counterfeit Deterrence Steering Committee), that the $10 note redesign set to precede the $20 redesign had already been delayed to no earlier than 2026 by 2016, and that the $20 note had not yet entered the banknote design process and was not expected to be production-ready until 2030.^[29]

Biden administration

In January 2021, White House Press Secretary Jen Psaki claimed President Joe Biden will accelerate the Tubman redesign.^[30] However, a 2022 internal department message from the Treasury Secretary, Janet Yellen, reaffirmed the 2030 debut originally planned by the Trump Administration.^[31][32]
