Got any suggestions? The government will be soliciting input from the public on a new website it plans to launch soon and on Twitter using the hashtag #TheNew10. "We're going to spend a lot of time this summer listening to people," said Treasury Secretary Jack Lew.
If you're looking for inspiration, you should know that at least 10 other nations, including Syria, the Philippines, and Israel, have already recognized female leaders on their banknotes—all of which you can see in the gallery below.
Syria's current image is that of a nation wracked by civil war and struggling against the violent militant group ISIS. But it outpaced the United States on one sign of social progress: recognizing women on official currency.
Syrian Queen Zenobia, known for fighting back against Roman colonizers in the second century AD, appears on the 500-pound note.
During the mid-1980s, the Philippines introduced a 500-peso note featuring prominent senator Benigno Aquino Jr., who had been assassinated in 1983. His wife, Corazon Aquino, went on to become the first female president of the Philippines—and the first female president in Asia, for that matter—and her image was added to the bill after she died in 2009. Early 20th-century suffragette Josefa Llanes Escoda also appears (alongside two men) on the 1000-peso note.
In Turkey, the current 50-lira note features turn-of-the-century novelist and women's rights activist Fatma Aliye Topuz on its reverse side. (The first president of Turkey, Mustafa Kemal Atatürk, appears on the front of every bill.)
Mexico's 500-peso note shows muralist Diego Rivera on the front and his wife and fellow artist Frida Kahlo on the back. Her image is a 1940 self-portrait, alongside a famous painting of hers from 1949, "Love's Embrace of the Universe, the Earth (Mexico), Myself, Diego and Señor Xólotl." Seventeenth-century Mexican writer Sor Juana Inés de la Cruz appears on the 200-peso note.
Argentina's beloved former First Lady Eva Perón—widely known by her nickname "Evita"—appears on the current 100-peso bill. The 20-peso note depicts 19th-century Argentine political activist Manuela Rosas along with her father, politician Juan Manuel de Rosas.
Like many other former British colonies, New Zealand features Queen Elizabeth II on its currency—the 20-dollar note to be precise. But Kiwi banknotes also honor suffragette Kate Sheppard, who in 1893 helped New Zealand become the first country in the world with universal voting rights for both men and women. Her image appears on the 10-dollar bill.
The Bank of Israel recently announced that it will be adding images of two female Israeli writers to forthcoming 20- and 100-New Shekel banknotes, respectively. The former will feature turn-of-the-century poet Rachel Bluwstein, and the latter author, poet, and literary expert Leah Goldberg, who died in 1970.
Imagery on the krona celebrates several women in Sweden's history. Currently there's Selma Lagerlöf—the first woman to win the Nobel Prize in Literature—on the 20-krona note, as well as 19th-century opera singer Jenny Lind on the 50-krona bill. Starting this fall, a new line of banknotes will feature Pippi Longstocking author Astrid Lindgren on the 20-krona, 20th-century soprano Birgit Nilsson on the 500-krona, and classic film actress Greta Garbo on the 100-krona note.
Australia has one woman on either the front or back of every banknote currently in circulation. They include Queen Elizabeth II on the front of the $5 bill, social reformer and writer Dame Mary Gilmore on the back of the $10, 19th-century businesswoman Mary Reibey on the front of the $20, politician and social worker Edith Cowan on the back of the $50, and turn-of-the-century soprano Dame Nellie Melba on the front of the $100 note.
If featuring women on currency were a contest, the Bank of England would win, with every note since 1960 depicting Queen Elizabeth II on the front. Past bills featured nurse and statistician Florence Nightingale on the back, current 5-pound notes show 19th-century social reformer Elizabeth Fry, and the next 10-pound bill will celebrate famed 19th-century author Jane Austen.
