Two-cent Billon
The two-cent billon was a pattern US coin struck in 1836 and initially proposed as part of the Act of January 13, 1837. Versions exist with either a reeded edge and coin orientation or a plain edge and medal orientation; however, those with the former tend to be original strikes, whereas the latter are always proof restrikes (most from the 1850s). Background A two-cent piece had been proposed as early as 1806 by Connecticut Senator Uriah Tracy, along with a twenty-cent piece or "double dime". Reflecting the then-prevalent view that coins should contain their value in metal, Tracy's bill provided that the two-cent piece be made of billon, or debased silver. The proposed metal would have consisted of 6.4 grains of silver and 24.3 grains of copper.http://twocentpiece.com/ The Mint Director at the time Robert Patterson opposed the bill, as it would be difficult to refine the silver from melted-down pieces. Tracy's legislation failed in the House of Representatives, despite pass ... [...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 ...

American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states that had seceded. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Decades of political controversy over slavery were brought to a head by the victory in the 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. An initial seven southern slave states responded to Lincoln's victory by seceding from the United States and, in 1861, forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. Led by Confederate President Jefferson Davis, ...

Currencies Introduced In 1836
A currency, "in circulation", from la, currens, -entis, literally meaning "running" or "traversing" is a standardization of money in any form, in use or circulation as a medium of exchange, for example banknotes and coins. A more general definition is that a currency is a ''system of money'' in common use within a specific environment over time, especially for people in a nation state. Under this definition, the British Pound Sterling (£), euros (€), Japanese yen (¥), and U.S. dollars (US$)) are examples of (government-issued) fiat currencies. Currencies may act as stores of value and be traded between nations in foreign exchange markets, which determine the relative values of the different currencies. Currencies in this sense are either chosen by users or decreed by governments, and each type has limited boundaries of acceptance - i.e. legal tender laws may require a particular unit of account for payments to government agencies. Other definitions of the term "currency ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Metal
The white metals are a series of often decorative bright metal alloys used as a base for plated silverware, ornaments or novelties, as well as any of several lead-based or tin-based alloys used for things like bearings, jewellery, miniature figures, fusible plugs, some medals and metal type. The term is also used in the antiques trade for an item suspected of being silver, but not hallmarked. A white metal alloy may include antimony, tin, lead, cadmium, bismuth, and zinc (some of which are quite toxic). Not all of these metals are found in all white metal alloys. Metals are mixed to achieve a desired goal or need. As an example, a base metal for jewellery needs to be castable, polishable, have good flow characteristics, have the ability to cast fine detail without an excessive amount of porosity and cast at between . Silver In compliance with British law, the British fine art trade uses the term "white metal" in auction catalogues to describe foreign silver items which d ...

Cupronickel
Cupronickel or copper-nickel (CuNi) is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. The copper content typically varies from 60 to 90 percent. (Monel is a nickel-copper alloy that contains a minimum of 52 percent nickel.) Despite its high copper content, cupronickel is silver in colour. Cupronickel is highly resistant to corrosion by salt water, and is therefore used for piping, heat exchangers and condensers in seawater systems, as well as for marine hardware. It is sometimes used for the propellers, propeller shafts, and hulls of high-quality boats. Other uses include military equipment and chemical, petrochemical, and electrical industries. Another common 20th-century use of cupronickel was silver-coloured coins. For this use, the typical alloy has 3:1 copper to nickel ratio, with very small amounts of manganese. In the past, true silver coins were debased with cupronickel, such as coins of the pound sterling from 1947 onwar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Billon (alloy)
Billon () is an alloy of a precious metal (most commonly silver, but also gold) with a majority base metal content (such as copper). It is used chiefly for making coins, medals, and token coins. The word comes from the French ''bille'', which means "log". History The use of billon coins dates from ancient Greece and continued through the Middle Ages. During the sixth and fifth centuries BC, some cities on Lesbos used coins made of 60% copper and 40% silver. In both ancient times and the Middle Ages, leaner mixtures were adopted, with less than 2% silver content. Billon coins are perhaps best known from the Roman Empire, where progressive debasements of the Roman ''denarius'' and the Roman provincial ''tetradrachm'' in the second century AD led to declining silver and increasing bronze content in these denominations of coins. Eventually, by the third quarter of the second century AD, these coins were almost entirely bronze, with only a thin coating or even a wash of silver. ...

Numismatics
Numismatics is the study or collection of currency, including coins, tokens, paper money, medals and related objects. Specialists, known as numismatists, are often characterized as students or collectors of coins, but the discipline also includes the broader study of money and other means of payment used to resolve debts and exchange goods. The earliest forms of money used by people are categorised by collectors as "Odd and Curious", but the use of other goods in barter exchange is excluded, even where used as a circulating currency (e.g., cigarettes or instant noodles in prison). As an example, the Kyrgyz people used horses as the principal currency unit, and gave small change in lambskins; the lambskins may be suitable for numismatic study, but the horses are not. Many objects have been used for centuries, such as cowry shells, precious metals, cocoa beans, large stones, and gems. Etymology First attested in English 1829, the word ''numismatics'' comes from the adjective ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pattern Coin
A pattern coin is a coin which has not been approved for release, but produced to evaluate a proposed coin design. They are often off-metal strike (using metals of lower value to test out the dies), to proof standard or piedforts. Many coin collectors collect and study pattern coins because of their historical importance. Many of the world's most valuable coins are pattern coins; nearly 25 of the pieces listed in ''100 Greatest US Coins'' are pattern coins. English patterns The first English coin that can be identified with certainty is a groat, originally worth fourpence. This piece, an example of which was illustrated and sold in the Dodsley Cuff sale of the mid-19th century, had crowns in place of the usual three pellets in each quarter of the reverse. Patterns are particularly identifiable and exist in larger numbers from the reign of Elizabeth I onwards. The experimental base metal issues of all coinage prior to the mid-18th century have been well preserved. Boulton's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salmon P
Salmon () is the common name for several commercially important species of euryhaline ray-finned fish from the family Salmonidae, which are native to tributaries of the North Atlantic (genus ''Salmo'') and North Pacific (genus '' Oncorhynchus'') basin. Other closely related fish in the same family include trout, char, grayling, whitefish, lenok and taimen. Salmon are typically anadromous: they hatch in the gravel beds of shallow fresh water streams, migrate to the ocean as adults and live like sea fish, then return to fresh water to reproduce. However, populations of several species are restricted to fresh water throughout their lives. Folklore has it that the fish return to the exact spot where they hatched to spawn, and tracking studies have shown this to be mostly true. A portion of a returning salmon run may stray and spawn in different freshwater systems; the percent of straying depends on the species of salmon. Homing behavior has been shown to depend on ...

James Pollock (American Politician)
James Pollock (September 11, 1810 – April 19, 1890) was the 13th governor of Pennsylvania from 1855 to 1858. Political career James Pollock graduated from the College of New Jersey at Princeton before setting up a law practice in his home community, in Milton, Pennsylvania. District attorney and judicial appointments followed and in 1844 he was elected to the United States House of Representatives where he served three successive terms. As a freshman congressman, Pollock boarded in the same rooming house as another new congressman, Abraham Lincoln (who would later become the 16th President of the United States), and they soon developed a mutual respect and longstanding friendship. Pollock was an early supporter of Samuel Morse and his idea for a telegraph and was instrumental in getting the United States Congress to appropriate a small amount to help build the first line. He was present in the room when the first message, "What hath God wrought" was received, ushering in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Civil War Token
Civil War tokens are token coins that were privately minted and distributed in the United States between 1861 and 1864. They were used mainly in the Northeast and Midwest. The widespread use of the tokens was a result of the scarcity of government-issued cents during the Civil War. Civil War tokens became illegal after the United States Congress passed a law on April 22, 1864, prohibiting the issue of any one or two-cent coins, tokens or devices for use as currency. On June 8, 1864, an additional law was passed that forbade all private coinage.Yeoman, R.S., ''A Guide Book of United States Coins'' (2004 edition), Whitman Publishing, 2003. Civil War tokens are divided into three types—store cards, patriotic tokens, and sutler tokens. All three types were utilized as currency, and are differentiated by their designs. The collectible value of the tokens is determined chiefly by their rarity. History By 1862, the second year of the Civil War, government-issued coinage began van ...

Franklin Peale
Benjamin Franklin Peale (born Aldrovand Peale; October 15, 1795 – May 5, 1870) was an employee and officer of the Philadelphia Mint from 1833 to 1854. Although Peale introduced many innovations to the United States Mint, Mint of the United States, he was eventually dismissed amid allegations he had used his position for personal gain. Peale was the son of painter Charles Willson Peale, and was born in the museum of curiosities that his father ran in Philadelphia. For the most part, Franklin Peale's education was informal, though he took some classes at the University of Pennsylvania. He became adept in machine making. In 1820, he became an assistant to his father at the museum, and managed it after Charles Peale's death in 1827. In 1833, Peale was hired by the Mint, and was sent for two years to Europe to study and report back on coining techniques. He returned with plans for improvement, and designed the first steam-powered coinage press in the United States, installed in ...
