As the story goes a mint employee, like many at the time, was a fan of the superman tv show. To signify his love of superman he struck an S mint mark in the chest of the eagle on the reverse of a die. Coins struck from this reverse die are the sought after Superbird variety. This is a nice example of this variety in PF66.
