as a phrase, 'dead presidents' is used for US paper currency--well, except for Hamilton and Franklin. today I learned of one more exception: Salmon P. Chase. he was Lincoln's Secretary of the Treasury, and as a wartime exigency, he reluctantly instituted paper currency. he was originally pictured on the 1-dollar bill and was known as Old Mr. Greenbacks until some years later when, now Chief Justice, he ruled that paper currency was unconstitutional! he later appeared on the $10,000 dollar-buck note, which was last printed in 1946. http://ask.yahoo.com/ask/19990420.html
