and yes, I know that all three of them are still alive, but that's only a minor detail that can be rectified before the coins go to mint.

 
Of course we also have Nancy Pelosi, AOC and Rashida Tlaib. Yes I know, same problem, same solution. lol

and classic porn star Seka.

Not because she probably ghost wrote LIttle House on the Prairie for her mother Laura Ingalls Wilder, but because she  founded the American libertarian movement.

Too little known to be put on a quarter, but maybe a dime?

Should TER make this a front page / landing page Poll Question?
.
The current poll Q is "Does the accuracy of photos affect your scoring of a session?"
.
Replace that with "What American woman should appear on the upcoming US Quarters?" Then a list of 5 to 10 nominees (with radio button selectors) as long as one choice is "Other". Then direct readers to this thread or to a new thread created by TER Admin to submit their "other" choices.
.
As poll votes accumulate on the 5-10 nominees, those with few votes are removed and and replaced by new choices, maybe once per week.  
.
Original list: Ana, Bella, Clara, Delia, Ella, Other.
Votes after one week: Ana 10, Bella 3, Clara 7, Delia 5, Ella 10, Other 22.
Goodbye Bella and Delia. Hello Frieda and Gina:
Ana 10, Clara 7, Ella 10, Frieda 0, Gina 0, Other 22.
Votes after the second week: Ana 12, Clara 8, Ella 14, Frieda 8, Gina 18. Other 29.  
Drop Clara; Keep Frieda (only one week on the list); Add Hilda. ... And so on.
