As a follow up to my Money: Faces on US Currency posting, Curt Moreno posed a question about coins. I felt compelled to respond. Since it is Friday, and I avoid technical posts on Fridays, here goes:

Denomination	Face on Coin	Image (source: Wikipedia)
1 cent penny	President Abraham Lincoln
5 cent nickel	President Thomas Jefferson
10 cent dime	President Franklin D. Roosevelt
25 cent quarter	President George Washington
50 cent half dollar	President John F. Kennedy
$1 dollar	First Woman to Vote, Susan B. Anthony
$1 dollar	Explorer Sacagawea

There are actually numerous $1 coins commemorative of US Presidents. The coins I have listed are the commonly used coins. So in terms of statesmen who are both bills and coins, the list would include: Abraham Lincoln (penny and $5 bill), Thomas Jefferson (nickel and $2 bill), and George Washington (quarter and $1 bill).

Unearthing common but uncommonly know facts is alive in the lab.
