5 min read

The dollar that Alexander Hamilton referred to as the "ancient dollar" was already a 250-year-old Spanish silver coin derived from a German-named piece minted in Bohemia, not a creation of the new American republic.

A coin that was never meant to be money

The story begins in the 1520s in a Bohemian valley where Count Stefan Schlick held disputed title to silver deposits. Because the mine operated outside normal royal oversight, investors from Saxony financed extraction and received their returns solely in large, high-value silver coins rather than a mix of big and small denominations. These coins, stamped as pure silver dividends, spread through Baltic trade and were copied by other city-states and kingdoms. The originals and their replicas became known as Joachimsthalers, shortened over time to thalers and then dollars in English usage. Spain later adapted the same weight and size standard for its own reales, producing the pieces of eight that circulated from the Andes to Manila and China. Colonial American ports competed with one another through currency devaluations to draw these coins ashore, because the silver itself remained the dominant medium of exchange long after political independence.

Show Notes

We love talking about money. And of course, we love talking about the dollar, in all its varieties — from bank deposits to eurodollars to stablecoins. But what fundamentally is a dollar and who actually controls it? To understand these questions, you need to understand how the dollar was born. Journalist (and current Ph.D. candidate in financial history) Brendan Greeley argues not only that the dollar is older than you might suspect, but that the dollar long precedes the United States itself. In fact, the word is derived from German, referring to a Spanish currency made from silver found in Mexico. In this episode, we discuss Brendan's new book, The Almighty Dollar: 500 Years of the World's Most Powerful Money. He explains not only the dollar's surprising history, but also what actually backs the US dollar and gives it purchasing power.
