Require all redesigns of bills to have a female and male version and set a date when all US currency will be 50% female.

Women represent 50% of the US population. They should have equal representation in all facets of our government, including our monetary system. Monetary notes are required to be redesigned to include tactile features for the blind, so with the announcement that a woman will be featured on some as yet to be determined percentage of $10 bills, I am urging the government to make the commitment that all future redesigns will include a female version and all printings will result in 50% of bills being the female version. This should also include a timetable for the redesigns to be completed, ending with the $100 as it was the most recently redesigned bill (released in 2013).
