I’m fairly certain that twenty-dollar bills are used more frequently. They’re what most ATMs spit out.
Before putting someone on money maybe we should first ask “what have they ever done for money?”
So what dead American woman has the greatest impact on our monetary system, or economy, of in banking or finance?
Elinor Ostrom is the only Nobel Prize winner in economics that is a woman. I’m not sure how influential that was and I only know about that myself because I looked it up just now. Seems to be for some interesting ideas who’s time is yet to come.
Is there anyone better from that field?
I recognize that Sojourner Truth and Eleanor Roosevelt did good things and are famous, but what lasting effect on American history did they have?
I still want Nellie Bly.
None of the women so far proposed seem to me to be of the same level of historical importance as any of the men in the current line-up. I think that parachuting in an affirmative action candidate would just emphasize the gap.
My nomination: “Walking Liberty”, formerly of the half-dollar:
Her story:
She represents core founding values of the country, so would make a suitable marker for the anniversary of the extension of rights to women. The design is very beautiful and full of resonant symbolism. Bonus – no ethnic or political baggage to quarrel over.
“Walking Liberty” FTW! 
I’d like to see Admiral Hopper, but could live with Rosa Parks, who is a significant figure in the civil rights movement, certainly a significant historical event. Less of a token than many other suggestions.
But, as many have already said, replace Jackson, not Hamilton.
Just wish it was the $20. I would like to see Jackson removed.
I’d like Clara Barton, or Harriet Beecher Stowe…
Clara Barton would be great.
Yep–Are $10 bills becoming rarer in circulation?. (That was nearly nine years ago, but I doubt the basic picture has changed.)
Life in plastic, it’s fantastic!
I would vote for her, but I think Susan B. Anthony will get in the ten.
so do I, given that they’re aligning it with the year women were granted the right to vote. plus, she’s already been represented on U.S. currency.
How many male scientists and engineers have graced our currency?
I suppose Hillary Clinton is out.
Most notably, Benjamin Franklin and Thomas Jefferson.
A few from a list of people on banknotes:
William Clark; Meriwether Lewis – explorers
DeWitt Clinton – father of the Erie Canal
Robert Fulton – Mr. Steamboat, and other engineering/invention accomplishments
Albert Gallatin – “the father of American ethnology” (Native American interests)
Samuel F. B. Morse – inventor of the telegraph
and those are just the names I recognized right off.
A lot of the military and naval types probably had some engineering background. Among non-currency presidents, that category included Dwight Eisenhower and Jimmy Carter.
More non-currency types: Theodore Roosevelt had extensive natural history interests. Herbert Hoover trained as a geologist and had a distinguished careet in engineering.
Maybe Rachel Dolezal? It seems to have been her idea. 
U.S. law prohibits living persons from being depicted on money, so people like Sandra Day O’Connor and Oprah Winfrey are out.
Betty Grable helped inspire American Servicemen to win WWII. Known as America’s Sweetheart. She worked tirelessly visiting wounded soldiers in the hospitals, and doing USO shows with Bob Hope very near the front lines. She was a big part of the US effort’s war bond drive.
She’d be a name people recognize and remember.
Why? Is he the most dead of all the dead presidents?
