The History of Money

What if your allowance came in the form of a massive rock? Hundreds of years ago, people on the island of Yap in the Pacific Ocean used giant stone discs as money. Many of the discs were taller than a person. Some weighed more than a car! Most never moved at all. The community simply agreed on who owned them.

That may sound strange, but money has taken a lot of unusual forms throughout history. People have used shells, cows, beads, and even whale teeth to buy and trade. In fact, money can be almost anything as long as people agree it has value. So how did we get from these early forms of currency to the dollars in your wallet—or the tap of your phone?

For most of human history, there was no such thing as money. If you needed something, you traded for it. A farmer with extra wheat might swap with a neighbor for eggs or a chicken. That’s called bartering—and if you’ve ever traded snacks with a friend, you’ve done it too.

But bartering presented a big problem: Both people had to want what the other had at exactly the same time. If the chicken owner didn’t need your wheat, there was no deal.

So people began using objects that people widely agreed were valuable. Most of this early money came from nature. In Africa, Asia, and the South Pacific, cowrie shells worked well because they were small, durable, and hard to fake. In other places, people used livestock or chunks of gold and silver. Precious metals (rare metals like gold, silver, and platinum) became especially popular because they could be divided into smaller amounts. But you had to weigh them out every time you bought something, and that was tedious. Imagine waiting in line for a taco while someone measured out lumps of silver!

Around 600 B.C., people in a kingdom called Lydia (in what is now Türkiye) came up with a faster way to pay. Craftsmen melted metal and turned it into ready-to-use pieces of standard weight: coins. Each coin was stamped with a roaring lion’s head, the symbol of Lydia’s king. That stamp acted like a guarantee. It told people the coin was real—and could be trusted.

Coins were a huge hit. Other kingdoms soon began minting their own. Later, the Romans used coins across a vast empire. Trade became faster, easier, and more reliable.

Still, metal money wasn’t perfect. It was quite heavy. Fill your pockets with enough coins and you’ll get a decent workout. More than a thousand years would pass before a lighter alternative appeared—all the way in China.

Money had been changing for thousands of years. But the next big shift wasn’t about what money was made of—it was about whether you needed to carry it at all. 

According to a famous story, the modern credit card was born out of an embarrassing event in New York City. In 1949, businessman Frank McNamara took clients out to eat—then realized he had forgotten his wallet. The incident inspired McNamara to invent a way to eat now, pay later. It was called the Diners Club card.

The idea was simple: Instead of paying cash at the end of a meal, cardholders could charge it using a (cardboard!) card. The credit card company covered the bill, and the customer paid later.

The first Diners Club cards, issued in 1950, could be used only at restaurants, but it didn’t take long for other companies and banks to create credit cards that worked elsewhere. Soon people could buy almost anything without cash.

That convenience came with a catch, though. Credit cards charge interest—meaning if you don’t pay your full bill each month, the amount you owe keeps growing. Today Americans owe about 

$1.28 trillion in credit card debt.

Some countries think they have the answer: digital cash. 

This new form of money is called a central bank digital currency, or CBDC. Cash is simple: You have a $10 bill, you hand it to someone, and you’re done. There’s no app, no bank, and no middleman involved. CBDCs would make digital money work the same way. Instead of a paper bill in your pocket, you’d have a digital token on your phone—issued directly by the government, not a bank.

As of mid-2025, 72 countries were in advanced stages of developing digital cash. In China, people already fork over digital yuan to pay for things from bus rides to takeout. So far, it’s been used to make more than $1 trillion worth of transactions. Other countries like the Bahamas, Jamaica, and Nigeria have also launched digital currencies. 

Supporters say “cashless cash” could make payments faster and cheaper. It would also help people who don’t have bank accounts pay electronically. But critics worry about security. Today money is spread across thousands of banks, which means that a hack into one bank doesn’t bring down the whole system. A CBDC would keep a whole country’s digital cash in one place, making it one very big target. What if hackers cracked the system and made off with piles of digital loot?

Perhaps the future of money is, well, you—or at least parts of your body. 

Already, at several Whataburger restaurants and other fast-food chains, people are buying fries with their faces. To sign up, a customer takes a selfie and links it to a payment method, like a bank account or a credit card. A computer scans the image and turns it into a kind of digital face map based on unique features, like the distance between the eyes. Later, when it’s time to pay, the customer simply looks at a camera near the register. If the face matches, the payment goes through—similar to how a face unlocks a smartphone.

The system has been shown to speed things up. Pay-by-face can save up to a minute and a half at checkout!

Amazon tried something similar with hands by installing palm scanners at all of its Whole Foods locations. They didn’t take off, though, and the futuristic payment system was recently shut down because too few people used it. 

These new ways to pay may be more efficient. But they come with hidden costs. For one thing, digital payments make it easier to spend without thinking. Studies have found that paying with cash hits your brain differently than tapping a phone. You see the money you earned from babysitting or mowing lawns leave your hand, and that makes the loss feel real. Scientists call this the “pain of paying.” But when you tap, spending becomes quick and invisible. That can trigger impulse buys.
