With abolitionist Harriet Tubman coming to the $20 bill, the women-on-currency issue deserves some context. Though men are featured on bank notes far more than women, the Tribune tracked down slightly more than 60 women portayed on paper money across the globe, including artists, diplomats, suffragists, educators, rulers, activists and national heroes.

Tubman would join an august group, among them at least 16 other women who fought for independence, women's rights or some other important cause. The queen of the sorority is an actual queen: Queen Elizabeth II, who thanks to the reach of the British Empire is featured on the bills of numerous territories that have their own currency.

The Tribune counted women on paper currency from 48 countires. Australia leads the world in its monetary equality with six women represented on currency. Each Australian denomination honors a woman on one side and a man on the other, with the exception of the $5 bill, which features just Queen Elizabeth II. After Australia, the best gender representation falls to Denmark (three of six featured people are women) and Japan (two of four).
