The story behind the coin
For most of American history, Liberty looked like a statue. She was a serene woman in a Greek robe — a borrowed goddess, restyled era after era. By the time the last classic Liberty left the coinage in the mid-twentieth century, she had stopped changing at all.
In 2015 the U.S. Mint decided to start the argument again. It struck the American Liberty High Relief gold coin — a one-ounce, 24-karat piece carrying a face value of $100. That number alone made history: it was the first $100 coin the United States had ever produced, and the highest face value ever placed on a U.S. gold coin.
But the denomination was the least interesting thing about it. The Mint, advised by its Citizens Coinage Advisory Committee (the citizen panel Congress created in 2003 to weigh in on coin designs), set out to do something genuinely new — to show Liberty as a living idea rather than a museum piece. Every two years since, the coin has been reissued with a brand-new design. The series has given America its first Liberty portrayed as an African-American woman, a Liberty rendered as a bucking wild mustang, and a Liberty that is simply an ancient tree. No other modern U.S. coin has been this willing to reinvent itself.
The "high relief" in the name is the secret to how it looks. Relief is how far a design rises off the flat field of the coin. Most coins are struck shallow so they stack and circulate easily. These are struck deep — the Mint feeds each blank through the press more than once — so the design stands up off the surface and catches the light like a small sculpture. It's the same effect that made the 1907 Saint-Gaudens double eagle the most admired coin America ever made, brought back on purpose.
