The story behind the coin
Around the year 1000, a Norse sailor named Leif Ericson stepped onto a coastline he called Vinland — almost certainly in what is now Newfoundland. He beat Christopher Columbus to the Americas by roughly 500 years. For most of the centuries since, the rest of the world barely noticed.
The year 2000 marked the millennium of that landing. To honor it, Congress passed the Leif Ericson Millennium Commemorative Coin Act, signed into law on December 6, 1999 (Public Law 106-126). The law called for a silver dollar "emblematic of the millennium of the discovery of the New World by Leif Ericson."
Here is what made it genuinely new. The same act tied the U.S. coin to a matching silver coin from Iceland — a 1,000-króna piece struck on the same blank, at the same Philadelphia Mint, at the same time. It was the first time the United States issued a commemorative coin jointly with another nation. Two countries, one anniversary, two coins minted under one roof. That had never happened before in American coinage.
