Its only money, after
3、all, and thats just what we use to buy the things we want and need. We get paid by our employers, and we use that money to pay tile bills, buy our food, and purchase goods and services. We might put some in a savings account at the bank or invest it in stocks or real estate, but for the most part, c
4、urrency seems like a fairly straightforward concept.In fact, the development of currency has shaped human civilization. Currency has stopped wars, and it has started many more. Cities and nations as we know them would not exist without it. It is difficult to overstate the importance of currency in m
5、odem life. Currency as SubstituteCurrency, or money, can be defined as a unit of purchasing power. It is a medium of exchange, a substitute for goods or services. It doesnt have to be the coins or bills with which youre probably most familiar. In fact, through the ages, everything from large stone w
6、heels, knives, slabs of salt, and even human beings have been used as money. Anything that people agree represents value is currency.For example, if you have one barrel of wheat, and you want a cow, without currency you have to find someone who not only has a cow, but also wants a barrel of wheat an
7、d will agree to the trade.Now, if you live in a place where round, stamped coins are widely considered to have a certain value and can be exchanged for other things, then you just have to find someone who needs wheat. That person will take the wheat in exchange for an agreed-upon amount of coins whi
8、ch you can later use to buy a cow from someone else.Currency as WealthBesides serving as a substitute in trades, moneys other important use is as a store of wealth. In a straight barter system, the commodities being traded are generally perishable. You can gather tons and tons of wheat by making shr
9、ewd trade deals, but if you try to save the wheat, it will eventually go bad. Money allows people to accumulate wealth.This had an enormous impact on civilization, because it meant that power wouldnt always be passed through families. People who had been excluded from any possibility of holding poli
10、tical power could amass wealth through trade or by providing a service. That wealth could then be used to purchase political or even military power. So money made civilization more democratic by taking some power out of the hands of noble families that had monopolized it for hundreds of years.Forms
11、of Currency: CommodityThe forms and functions of currency have changed over the last 3,000 years or so, generally falling into four categories:Commodity currencyCoinsPaper moneyElectronic currencyCommodity CurrencyThe development of commodity-based currency systems represents more of a blurring betw
12、een barter systems and later currency systems than a revolutionary change. In a commodity system, the money used is not only a “place-holder“ for purchasing power, but it is something that has an inherent value by itself.A good example of a commodity system is the one used by the Aztecs. They placed
13、 great value on cacao beans, which could be used to make chocolate. The beans were small and easy to carry, so they were often used to balance out or make change in barter agreements.Forms of Currency: CoinsThe first coins were minted in Lydia, an ancient empire in the area of modem Turkey. The Lydi
14、an king Croesus started making small metal ingots stamped with an imperial emblem around 640 B. C.This Lydian custom spread to the Greeks and eventually to the Romans. Coins were usually made of silver or gold, and their value was enforced by the authority of the government that issued them. If the
15、Athenian officials declared that all coins minted in Athens, with the official stamp of Athens, were 97 percent silver, then those coins would be traded at that value.In China, coins developed at about the same time that they did in the West. In the fifth century B. C. , the Chinese began using a fo
16、rm of commodity currency in the shape of knives or other tools. The metal blades had a round hole at one end, so the money could be strung onto a rod or rope. Eventually, the tools became more stylized. Over the years, they became smaller and smaller, until only the round end with a hole in it was l
17、eft. These round, pierced Chinese coins remained virtually unchanged until the 1800s.Forms of Currency: PaperPaper money was developed first by the Chinese, who used stag skins, bark, or parchment marked with the imperial seal as “bills of payment.“ The penalty for counterfeiting was death.Paper mon
18、ey had trouble gaining acceptance in Europe. Leather money was used around 1100, but only as a temporary substitute when silver supplies ran low. A Swedish bank issued paper money in 1661, but they eventually flooded the market with it, and it lost its value.The use of paper money really caught on i
19、n Europe in the 1700s, when the official bank of the French government began issuing paper money. The idea came from goldsmiths, who often gave people bills of receipt for their gold. The bills could be exchanged for the gold at a later date. Thats an important fact in the development of paper money
20、, because it means that the money represented a real amount of gold or silver that actually existed somewhere. A piece of money was actually a promise from the institution that issued it( either a government or a bank)that the institution would give the holder of the hill a certain amount of gold or
21、 silver from its stockpile whenever he wanted it.

22、nce money is really just a representation of value, it didnt take long for people to realize they could just send information about money by telegraph or other electronic means, and it was just as “real“ as sending the money itself. After World War , banks would record information about the days tra

This system eliminated the need for the large denominations that were printed prior to the war to facilitate these large-scale transfers. Today, the $ 500, $1,000, $ 5,000, and $10,000 bills printed during th
