Money is any item or verifiable record accepted as payment. It allows people to buy goods and services. It also allows them to repay debts, such as taxes.

In modern times, money is often unbacked by physical goods. This type of money is called fiat money. Its value comes from social convention and government decree. In the United States, the dollar is legal tender. This means it must be accepted for all public and private debts.

Money performs several essential functions in an economy. The first is acting as a medium of exchange. This role helps avoid the problems of a barter system. In barter, people must find a "coincidence of wants." This means one person must have exactly what the other person needs. A medium of exchange removes this burden. It allows people to specialize in different tasks. The second function is acting as a unit of account. This provides a standard numerical measurement for market value. It allows for clear pricing and efficient bookkeeping.

A third vital function is acting as a store of value. This means money must be reliably saved and retrieved. Its value should remain stable over time so it can be used later. Some older texts also include a fourth function. They call it a standard of deferred payment. This is an accepted way to settle debts over time. It allows people to buy things now and pay for them later. However, many modern textbooks group this under the other three functions.

For money to work, it must have specific properties. It must be fungible, meaning units are interchangeable. It must be durable so it survives repeated use. It also needs to be divisible into smaller units. Portability is necessary so it can be easily carried. Most importantly, it must be acceptable to the public. Finally, the supply must be scarce to maintain its value.

The history of money shows a long evolution. Some scholars believe barter-like methods existed 100,000 years ago. However, many societies used gift economies or debt instead. Later, many cultures used commodity money. This is money that has intrinsic value. For example, the Mesopotamian shekel was a unit of weight. It relied on the mass of 160 grains of barley. Other societies used cowry shells as money.

Stamped coins appeared much later in history. The Lydians are credited by Herodotus with introducing gold and silver coins. Modern scholars date these coins to around 650 to 600 BC.

Eventually, systems evolved into representative money. Merchants issued receipts for gold or silver deposits. These receipts eventually became a way to pay for things. The Song dynasty in China created the first paper money called jiaozi.

In Europe, the gold standard became common between the 17th and 19th centuries. This meant paper notes could be exchanged for fixed amounts of gold.

Modern money systems changed significantly in the 20th century. After World War II, many countries used currencies fixed to the U.S. dollar. The U.S. dollar was itself fixed to gold. This changed in 1971 when the U.S. suspended gold convertibility. Most currencies became unbacked fiat money after this time. Today, the money supply includes more than just coins and bills. It includes bank money, such as checking and savings balances. In developed countries, bank money is the largest part of broad money.
