The $1 Face Value set of two Silver Franklin half dollars is an amazing representation of one of America's brightest inventors - Benjamin Franklin, one of the founding fathers of the United States. The production of Franklin half dollar silver coins was halted once the Kennedy half dollars were introduced. This made the $1 face value set of Franklin Half dollars more desirable than before. The average circulation of Franklin half dollars can be dated back from 1948 to 1963. The design was created by John R. Sinnock.
