WASHINGTON (MEDIA GENERAL) – Harriet Tubman will be the new face of the $20 bill in what will be the first change of the portrait on any U.S. currency in nearly 90 years.

Treasury Secretary Jacob Lew is expected to make the official announcement as well as provide details on other changes being made to the $20, $10 and $5 bills.

Tubman’s portrait will replace President Andrew Jackson, who has been on the $20 bill since 1929.

The faces on U.S. currency have changed very little over the years. Below is the history.

$1 Bill: George Washington

The first $1 notes (called United States Notes or “Legal Tenders”) were issued in 1862 and featured a portrait of Secretary of the Treasury Salmon P. Chase (1861-1864). The first use of George Washington’s portrait on the $1 bill was in 1869.

$2 Bill: Thomas Jefferson

The first $2 notes were issued in 1862 and featured a portrait of the first secretary of the treasury, Alexander Hamilton (1789-1795). The first use of Thomas Jefferson’s portrait on $2 bills was in 1869.

$5 Bill: Abraham Lincoln
