The Nina Otero-Warren Quarter is the fourth coin in the American Women Quarters™ Program. Nina Otero-Warren was a leader in New Mexico’s suffrage movement and the first woman to be superintendent of Santa Fe public schools.

Otero-Warren emphasized the necessity of using the Spanish language in the suffrage fight in order to reach Hispanic women. She also spearheaded the lobbying effort to ratify the 19th Amendment in New Mexico.

Otero-Warren strove to improve education for all New Mexicans and worked to advance bicultural education and to preserve cultural practices among the state’s Hispanic and Native American communities.

In 1921, she became the first Hispanic woman to run for Congress, although she was defeated in the general election.
