1 Dollar (Benjamin Franklin Tercentenary, Founding Father)

The 2006 Benjamin Franklin 'Founding Father' Silver Dollar

For Franklin's 300th birthday, the U.S. Mint did something clever: it put a coin on a coin. The reverse of this 2006 silver dollar reproduces the 1776 Continental dollar — the very first pattern dollar the new nation tried to strike, designed, the story goes, by Franklin himself. Right down to its odd, blunt motto: "Mind Your Business."
