Step 1 : Introduction to the question "Which president is pictured on the U.S. paper currency that has the White House on the back?"
...The seventh U.S. President, Andrew Jackson is featured on the front side of the $20 bill since 1928; the White House is featured on the reverse. The placement of Jackson on the $20 bill may be a historical irony; as president, he vehemently opposed both the National Bank and paper money and made the goal of his administration the destruction of the National Bank. In his farewell address to the nation, he cautioned the public about paper money. The average circulation life of a $20 bill is 7.9 years before it is replaced due to wear.
