Franklin Half Dollars

The Benjamin Franklin Half Dollar coin marked the first time a US Half Dollar did not picture an allegorical portrait of Liberty.  Instead, it features the portrait of well-loved Founding Father, Benjamin Franklin on the "heads" side and the Liberty Bell on the "tails" side.  It was produced from April 30, 1948, to late 1963, and was made of 90% pure silver.  It was replaced by the Kennedy Half Dollar.
