Pirates, Pieces of Eight, and the $ in Your Pocket

A few weeks ago, my grandson and I were playing a links course on the north coast of Ireland. While we waited on the third tee for the group ahead, a retired American arrived on a solo round. We got talking and ended up playing the rest of the course together, picking up a masterclass in golf along the way. He turned out to have been hired by the PGA Tour in the early days of social media to follow Tiger Woods around with a camera, helping start the digital media trend we now take for granted. At the end of the round he gave my grandson a real silver dollar to use as a ball marker.

That coin got me wondering where the dollar and its symbol came from. So, with a hot mug of coffee and plenty of time to read, I’ve spent a couple of hours diving into early financial history. Take the $ sign. Most people assume the founding fathers cooked it up: an uppercase U stamped over an S for “United States,” with the bottom curve snipped off by lazy clerks. It sounds plausible, but it’s not true. The symbol predates the American Republic by a good stretch, and its story involves 18th-century trade routes, fast-writing accountants, and Spanish silver.

Long before stock markets or central banks, the western world ran on one particular silver coin: the Spanish peso, officially the real de a ocho, or “piece of eight.” Minted by the millions from silver in Mexico and Bolivia, its consistent weight and purity made it the world’s first true global currency. It was accepted everywhere, from Asian trading posts to colonial taverns, and it was the main cargo on transatlantic galleons, which made it the favorite target of pirates and privateers. Colonial merchants had no single national currency, so they recorded almost everything in pesos, and to save ink, accountants abbreviated “pesos” to ps.

Scribble a p and an s on top of each other fifty times in a hurry and the loop of the p vanishes into the stroke while the s settles over the stem. By the 1770s, in the ledgers of merchants supplying the American Revolution, most notably the Irish-American trader Oliver Pollock, the ps had become a single character: an S sliced by a vertical line. When Congress passed the Mint Act in 1792, it based the new currency on the weight of the familiar Spanish coin, and simply pinched the shorthand merchants were already using: $.

The piece of eight also shaped how we talk about money. Small change was scarce in the 1700s, so merchants chopped the silver coin into eighths with a chisel. Each slice was one real, or a “bit.” Two bits made 25 cents, which is why a quarter is still called “two bits.” The system lingered in finance too: Wall Street priced stocks in fractions for over two hundred years, only switching to decimals in April 2001.

Modern money is slick and digital, but it still rests on trust, convention, and habit. The symbol beside your bank balance is just the surviving shorthand of clerks counting silver pieces of eight.

Which brings me back to that coin on the links. I’ll always be grateful to our American friend for the golf lessons, but I suspect the silver dollar will outlast them. Every time my grandson marks his ball, he’ll be holding a small piece of that history. And unlike the paper dollar in your pocket, which seems to lose purchasing power by the back nine, his silver eagle is busy outperforming my retirement portfolio. It’s a nice reminder of the day a stranger on the links became a friend for the afternoon—and left my grandson with a dollar that actually holds its value. 😉
