Chain Cent
The chain cent was America's first large cent and the first circulating coin officially produced by the United States Mint. It was struck only during 1793. It was not the first circulating coin produced by the United States, which was the Fugio cent of 1787 (also known as the Franklin cent), based on the Continental dollar. As with the Fugio cent, the Chain cent was made of copper and featured a chain symbolizing the linking together of the states of the United States. Obverse design The obverse design consisted of a stylized Liberty head with flowing hair. The inscription "LIBERTY" appeared above the portrait, and the date below. The design was rather sparse and empty compared to those that would come later. Reverse design The reverse's central design figure, for which the coin is named, is an interlocking chain with 15 links, representing the 15 American states in existence at that time. Both the words "ONE CENT" and the fraction "1/100" appear within the chain. Along the outer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Coining (mint)
Minting, coining or coinage is the process of manufacturing coins using a kind of stamping, the process used in both hammered coinage and milled coinage. This "stamping" process is different from the method used in cast coinage. A coin die is one of the two metallic pieces that are used to strike a coin, one per each side of the coin. A die contains an inverse version of the image to be ''struck'' on the coin. ''Striking'' a coin refers to pressing an image into the blank metal disc, or planchet, and is a term descended from the days when the dies were struck with hammers to deform the metal into the image of the dies. Modern dies made out of hardened steel are capable of producing many hundreds of thousands of coins before they are retired and defaced. Ancient coin dies Prior to the modern era, coin dies were manufactured individually by hand by artisans known as engravers. In demanding times, such as the crisis of the Roman Empire in the 3rd century, dies were still used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cent (United States Coin)
The cent, the United States one-cent coin (symbol: ¢), often called the "penny", is a unit of currency equaling one one-hundredth of a United States dollar. It has been the lowest face-value physical unit of U.S. currency since the abolition of the half-cent in 1857 (the abstract mill, which has never been minted, equal to a tenth of a cent, continues to see limited use in the fields of taxation and finance). The first U.S. cent was produced in 1787, and the cent has been issued primarily as a copper or copper-plated coin throughout its history. The penny is issued in its current form as the Lincoln cent, with its obverse featuring the profile of President Abraham Lincoln since 1909, the centennial of his birth. From 1959 (the sesquicentennial of Lincoln's birth) to 2008, the reverse featured the Lincoln Memorial. Four different reverse designs in 2009 honored Lincoln's 200th birthday and a new, "permanent" reverse – the Union Shield – was introduced in 2010. The coin is ...

Business Strike
A circulation issue or circulation coin,_ (1988). ''The American Coin Redesign Act'', Volume 4, by United States Congress Senate Committee on Banking, Housing, and Urban Affairs. sometimes called a business strike (US), is a coin minted and issued for commerce as opposed to those made as commemorative coins and proof coins. Circulation issue coins are normally produced in relatively large numbers, and are primarily meant to be used as pocket change, not collected. Even though special collector coins, such as proof coinage Proof coinage refers to special early samples of a coin issue, historically made for checking the dies (as in demonstrating that something is true) and for archival purposes. Nowadays proofs are often struck in greater numbers specially for co ..., are produced in smaller numbers, the circulation issue coins are sometimes more valuable in high grade than their proof counterparts. This is because whereas proof coins are almost always carefully preserved by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wreath Cent
The Wreath cent was an American large cent. It was the second design type, following the Chain cent in 1793. It was produced only during that year. Obverse design The obverse design consisted of a stylized Liberty head with flowing hair. The inscription "LIBERTY" appeared above the portrait. Below it was a three-leaved sprig and the date. The design of the Liberty head was modified somewhat from that of the Chain cent to address public criticism. Reverse design The reverse's central design figure, for which the coin is named, was a wreath. The words "ONE CENT" appeared within the wreath, and the corresponding fraction "1/100" appeared beneath it. Along the outer edge was inscribed "UNITED STATES OF AMERICA". A decorative beaded border was added along the rim. Varieties Approximately 63,353 Wreath cents were struck. Early specimens featured a stylized "vine/bars" design on the edges of the planchet, which was identical to that of the earlier Chain cent. Later on, this was c ...

Planchet
A planchet is a round metal disk that is ready to be struck as a coin. An older word for planchet is flan. They are also referred to as blanks. History The preparation of the flan or planchet has varied over the years. In ancient times, the flan was heated before striking because the metal that the coin dies were made of was not as hard as dies today, and the dies would have worn faster and broken sooner had the flan not been heated to a high temperature to soften it. An unusual method was used to mint the one-sided, bowl-shaped ''pfennigs'' of the Holy Roman Empire. The planchet used for these so-called ''Schüsselpfennigs'' was larger than the coin die itself. The coins were made by striking with only one upper die on the larger planchet. As a result, the perimeter of the planchet was pressed upwards in the shape of a bowl or plate. Until the 18th century they were minted mainly in the Harz Mountains. The curved shape of the pfennig was very useful for handling small change ...

History Of Slavery In The United States
The legal institution of human chattel slavery, comprising the enslavement primarily of Africans and African Americans, was prevalent in the United States of America from its founding in 1776 until 1865, predominantly in the South. Slavery was established throughout European colonization in the Americas. From 1526, during early colonial days, it was practiced in what became Britain's colonies, including the Thirteen Colonies that formed the United States. Under the law, an enslaved person was treated as property that could be bought, sold, or given away. Slavery lasted in about half of U.S. states until abolition. In the decades after the end of Reconstruction, many of slavery's economic and social functions were continued through segregation, sharecropping, and convict leasing. By the time of the American Revolution (1775–1783), the status of enslaved people had been institutionalized as a racial caste associated with African ancestry. During and immediately follow ...

Continental Currency
Early American currency went through several stages of development during the colonial and post-Revolutionary history of the United States. John Hull was authorized by the Massachusetts legislature to make the earliest coinage of the colony (the willow, the oak, and the pine tree shilling) in 1652. Because few coins were minted in the Thirteen Colonies, which later became the United Colonies and then the United States, foreign coins like the Spanish dollar were widely circulated. Colonial governments, at times, issued paper money to facilitate economic activities. The British Parliament passed Currency Acts in 1751, 1764, and 1773 to regulate colonial paper money. During the American Revolution, the Colonies became independent states. No longer subject to monetary regulations arbitrarily imposed by the British Parliament, the States began to issue paper money to pay for military expenses. The Continental Congress also issued paper money during the Revolution — known as Conti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

David Rittenhouse
David Rittenhouse (April 8, 1732 – June 26, 1796) was an American astronomer, inventor, clockmaker, mathematician, surveyor, scientific instrument craftsman, and public official. Rittenhouse was a member of the American Philosophical Society and the first director of the United States Mint. Biography David Rittenhouse was born on April 8, 1732, in Roxborough Township, Philadelphia County, near a small village within Philadelphia called Rittenhousetown. This village is located near Germantown, along the stream Paper Mill Run, which is a tiny tributary of the Wissahickon Creek. When his uncle, William Rittenhouse, died, David inherited his uncle's carpentry tools and instructional books. At a young age, David showed a high level of intelligence by creating a working scale model of his great-grandfather William Rittenhouse's paper mill. He built other scale models in his youth, like a working waterwheel. David never attended elementary school—he was self-taught from his f ...

Die (manufacturing)
A die is a specialized machine tool used in manufacturing industries to cut and/or form material to a desired shape or profile. Stamping dies are used with a press, as opposed to drawing dies (used in the manufacture of wire) and casting dies (used in molding) which are not. Like molds, dies are generally customized to the item they are used to create. Products made with dies range from simple paper clips to complex pieces used in advanced technology. Continuous-feed laser cutting may displace the analogous die-based process in the automotive industry, among others. Die stamping Blanking and piercing are two die cutting operations, and bending is an example of a die forming operation. Die forming Forming operations work by deforming materials like sheet metal or plastic using force (compression, tension, or both) and rely on the material's mechanical properties. Forming dies are typically made by tool and die makers and put into production after mounting into a press. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
