Silver coin

regarded as a luxury item. Its inherent scarcity gave gold value and it became a symbol of status and wealth because those who could afford to frivolously spend on jewelry were well-off. In some societies, it even became a currency, shaped into round coins and emblazoned with faces of rulers. The rarity, usefulness, and desirability of gold made it a great long-term store of value, and it therefore went on to become a standard that backed other forms of currency. 5,000 years of various…

Gold is widely used in modern day medicine to treat disorders. This is because gold is very resistant to bacteria. Bacteria are microscopic single-celled organisms. Bacteria are prokaryotes, meaning the entire organism consists of a single cell with a simple internal structure. The DNA of a prokaryote is neatly packed in the nucleus. The bacterial DNA floats freely in a twisted thread-like mass called the nucleoid. Gold is unaffected by almost everything. The only materials that can affect gold…

One of the earliest metals to be discovered, lead has a long history with mankind. It was first discovered around 7000 BC as a byproduct of silver smelting. Lead is metal known for its resistance against corrosion, malleability, and low melting point. Mined all across the world, lead was one of the most important metals in ancient times. Although lead was toxic, it was used widely, particularly in the Roman Empire. Through its uses and toxicity, lead affected the classical era in a drastic way.…

A polymer is a large molecule which is formed by repeated linkage of small molecule called monomers. Conducting polymer have been the subjects for many decades as possible synthetic metals. Many of these polymer, especially those with a conjugated pi-bond system ,often yield higher conductivity once having undergone the doping process. Polymers are typically insulators due to their very high resistivity .Insulators have tightly bound electrons so that nearly no electron flow occurs ,and they…

occasionally during the 19th century. Platinum was only occasionally used because it’s too hard to be formed in to a foil. [2] Silver was a popular filling also during the 19th century but like platinum was hard to be used. Both silver and platinum are less malleable then gold is. [2] Amalgam has been used for many years and is still used today. During the civil war silver, tin, mercury fillings were mostly used. This material was placed where the gold couldn’t fit also. Amalgam when set is…

The Two Faces of a Political Coin A society depends greatly on the person who is leading it. If a leader is just and morally sound, his/her society prospers and flourishes. However, if a leader is corrupt and abuses his/her power, the society inevitably falls into turmoil and disaster. Suzanne Collins represents this through Katniss Everdeen, as she demonstrates through Katniss’s inner thoughts why President Alma Coin is eliminated and not given the chance to become leader of Panem. In…

The one-cent coin was the first piece of currency authorized by the United States government in 1793. Also included was the half-cent, dime and quarter-dollar. Today, one will probably not recognize the name or face of the half-cent. This is because it was discontinued in 1857 due to its lack of value and failure to facilitate trade. In recent years, the penny has taken to many of the same effects the half-cent had in the mid-1800’s. The penny has lost its value in the functioning economy and…

Since the beginning of civilization and the start of a national currency, there has been counterfeiting. Nowadays paying in cash is an afterthought that U.S. citizens take for granted neither the customer or the clerk give more than a courtesy glance. This is because both people believe that bill is genuine. However this was not always the case. In the beginning of the United States of America, many people did not trust the money they received nor did they trust their government that was made by…

In 1792 the currency of the United States penny was developed. The circle shaped structure was twice the size of the current penny as we know today. The penny was the United States first currency and Benjamin Franklin is to thank for that. The penny represents the foundation of our country and shows how much we have grown as a nation. But there has been a lot of controversy on whether or not the penny should be kept due to the fact it cost more to make the penny than it is to use it as currency…

For example, the military don't use pennies overseas because they aren't cost effective to ship because they are worth so little(Mancused). The military dropped the coin without consequences and so could the U.S. Also, Pennies aren't worth much by themselves, so people wouldn't mind giving them up(Waterhouse). Most people don't even use pennies anymore. .People also throw most of their pennies in fountains and in their…
