The story behind the coin
September 17, 1987 marked two hundred years since thirty-nine men signed the U.S. Constitution in Philadelphia. Congress wanted the anniversary marked in metal — and it wanted the coins to do something useful while they were at it.
The Bicentennial of the Constitution Coins and Medals Act (Public Law 99-582), signed into law on October 29, 1986, authorized two coins: a silver dollar and this $5 gold piece — a "half eagle," the traditional name for the United States' five-dollar gold denomination. The law capped the gold coin at one million pieces and attached a $35 surcharge to every one sold.
Here is the unusual part. That surcharge was earmarked, by statute, for the general fund of the Treasury for the sole purpose of reducing the national debt. Most commemorative coins raise money for a museum, a memorial, or an organizing committee. This one was sold, in part, to chip away at what the country owed. It is a rare case of a coin with a fiscal mission baked into the law that created it.
The program was a single-year affair — struck only in 1987, never repeated — and it sold briskly. Across both the silver dollar and this gold half eagle, the Constitution program moved millions of coins and sent tens of millions of dollars in surcharges toward the debt. For a modern commemorative, that was a genuine success.
