There are numerous myths about the origins of money. The concept of money is often confused with coinage. Coins are a relatively modern form of money. Their first appearance was probably in Asia in the 7th century BC. And whether these coins were used as money in the modern sense has also been questioned.
To determine the earliest use of money, we need to define what we mean by money. We will return to this issue shortly. But with any reasonable definition the first use of money is as old as human civilization. The early Persians deposited their grain in state or church granaries. The receipts of deposit were then used as methods of payment in the economies. Thus, banks were invented before coins. Ancient Egypt had a similar system, but instead of receipts they used orders of withdrawal – thus making their system very close to that of modern checks. In fact, during Alexander the Great’s period, the granaries were linked together, making checks in the 3rd century BC more convenient than British checks in the 1980s.
However, money is older than written history. Recent anthropological and linguistic research indicates that not only is money very old, but it’s origin has little to do with trading, thus contradicting another common myth. Rather, money was first used in a social setting. Probably at first as a method of punishment.
Early Stone Age man began the use of precious metals as money. Until the invention of coins, metals were weighed to determine their value. Counting is of course more practical, the first standardized ingots appeared around 2200 BC. Other commonplace objects were subsequently used in the abstract sense, for example miniature axes, nails, swords, etc.
