People who deserve to be on US Currency:
Edward Everett ($50 1878 & 1891)
Michael Hillegas ($10 1907)
James Madison ($5000 1878)
Not the tried and failed:
Susan B. Anthony ($1 coin, 1979)
If there were to be a woman on our currency, might I suggest the 1916 quarter as a template? Very appropriate for the state of American Culture. 🙁
