1851 $50 Humbert
The 1851 Humbert $50 gold ingot was an Ingot produced by Moffat and Company, under the direction of Augustus Humbert (U.S. Assayer of the treasury) This "coin", while technically an ingot, was still used and unofficially considered currency. It was also the largest ingot produced during the California Gold Rush, weighing almost 2.5 oz. During the gold rush of 1849, the US Treasury department hired private companies to mint coins before they could properly set up a mint. The U.S. Treasury was much more practical and would often mint coins near the location of the precious metals used in the coins, however, this did not always happen overnight. Augustus Humbert, who was originally a watchmaker from NY, took a lifestyle change and moved out to California during the gold rush in 1850. The U.S. Treasury had commissioned him to be an assay An assay is an investigative (analytic) procedure in laboratory medicine, mining, pharmacology, environmental biology and molecular biology for q ...

Gold Ingot
A gold bar, also called gold bullion or gold ingot, is a quantity of refined metallic gold of any shape that is made by a bar producer meeting standard conditions of manufacture, labeling, and record keeping. Larger gold bars that are produced by pouring the molten metal into molds are called ingots. Smaller bars may be manufactured by minting or stamping from appropriately rolled gold sheets. The standard gold bar held as gold reserves by central banks and traded among bullion dealers is the Good Delivery gold bar. The kilobar, which is in mass, and a 100 troy ounce gold bar are the bars that are more manageable and are used extensively for trading and investment. The premium on these bars when traded is very low over the spot value of the gold, making it ideal for small transfers between banks and traders. Most kilobars are flat, although some investors, particularly in Europe, prefer the brick shape. Types Based upon how they are manufactured, gold bars are categorized as ...

Ingot
An ingot is a piece of relatively pure material, usually metal, that is cast into a shape suitable for further processing. In steelmaking, it is the first step among semi-finished casting products. Ingots usually require a second procedure of shaping, such as cold/hot working, cutting, or milling to produce a useful final product. Non-metallic and semiconductor materials prepared in bulk form may also be referred to as ingots, particularly when cast by mold based methods. Precious metal ingots can be used as currency (with or without being processed into other shapes), or as a currency reserve, as with gold bars. Types Ingots are generally made of metal, either pure or alloy, heated past its melting point and cast into a bar or block using a mold chill method. A special case are polycrystalline or single crystal ingots made by pulling from a molten melt. Single crystal Single crystal ingots (called boules) of materials are grown (crystal growth) using methods such as the Czo ...

Mount Ophir is a ghost town in Mariposa County, California. It was a mining town founded in 1850 during the California Gold Rush, and was the site of the Mount Ophir Mint, the first authorized mint in California. History Mount Ophir during the early 1850s was a large camp, and stores and tents straggled along the main road for quite a distance. In 1854, Louis Trabucco purchased the stone-walled trading post in Mount Ophir, which was patronized by miners and packers. Its ruins now stand next to the foundation of a large two-store frame hotel built in 1852. The Post Office opened in 1852 under the name "Ophir" but was changed in 1856 to "Mount Ophir" because of the name conflict with Ophir in Placer County Placer County ( ; Spanish for "sand deposit"), officially the County of Placer, is a county in the U.S. state of California.

California Gold Rush
The California Gold Rush (1848–1855) was a gold rush that began on January 24, 1848, when gold was found by James W. Marshall at Sutter's Mill in Coloma, California. The news of gold brought approximately 300,000 people to California from the rest of the United States and abroad. The sudden influx of gold into the money supply reinvigorated the American economy; the sudden population increase allowed California to go rapidly to statehood, in the Compromise of 1850. The Gold Rush had severe effects on Native Californians and accelerated the Native American population's decline from disease, starvation and the California genocide. The effects of the Gold Rush were substantial. Whole indigenous societies were attacked and pushed off their lands by the gold-seekers, called "forty-niners" (referring to 1849, the peak year for Gold Rush immigration). Outside of California, the first to arrive were from Oregon, the Sandwich Islands (Hawaii) and Latin America in late 1848. Of th ...

Metallurgical Assay
A metallurgical assay is a compositional analysis of an ore, metal, or alloy, usually performed in order to test for purity or quality. Some assay methods are suitable for raw materials; others are more appropriate for finished goods. Raw precious metals (bullion) are assayed by an assay office. Silver is assayed by titration, gold by cupellation and platinum by inductively coupled plasma optical emission spectrometry (ICP OES). Precious metal items of art or jewelry are frequently hallmarked (depending upon the requirements of the laws of either the place of manufacture or the place of import). Where required to be hallmarked, semi-finished precious metal items of art or jewelry pass through the official testing channels where they are analyzed or assayed for precious metal content. While different nations permit a variety of legally acceptable finenesses, the assayer is actually testing to determine that the fineness of the product conforms with the statement or claim of fin ...

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] |
