Troy weight is a system of units of mass that originated in 15th-century England, and is primarily used in the precious metals industry. The Troy weights are the grain, the pennyweight, the troy ounce, and the troy pound. The troy grain is equal to the grain-unit of the avoirdupois system, the troy ounce is heavier than the avoirdupois ounce, yet the troy pound is lighter than the avoirdupois pound.
Precious metals are rare, naturally occurring metallic chemical elements of high economic value. Chemically, the precious metals tend to be less reactive than most elements. They are usually ductile and have a high lustre. Historically, precious metals were important as currency but are now regarded mainly as investment and industrial commodities. Gold, silver, platinum, and palladium each have an ISO 4217 currency code.
The ounce is the name of several different units of mass, weight, or volume used in most British derived customary systems of measurement.
The dime, in United States usage, is a ten-cent coin, one tenth of a United States dollar, labeled formally as "one dime". The denomination was first authorized by the Coinage Act of 1792. The dime is the smallest in diameter and is the thinnest of all U.S. coins currently minted for circulation, being 0.705 inches in diameter and 0.053 in (1.35 mm) in thickness. The obverse of the current dime depicts the profile of President Franklin D. Roosevelt and the reverse boasts an olive branch, a torch, and an oak branch, from left to right respectively. As of 2011, the dime coin cost 5.65 cents to produce.
The eagle was a United States $10 gold coin issued by the United States Mint from 1792 to 1933.
A debasement of coinage is the practice of lowering the intrinsic value of coins, especially when used in connection with commodity money, such as gold or silver coins. A coin is said to be debased if the quantity of gold, silver, copper or nickel in the coin is reduced.
The fineness of a precious metal object represents the weight of fine metal therein, in proportion to the total weight which includes alloying base metals and any impurities. Alloy metals are added to increase hardness and durability of coins and jewelry, alter colors, decrease the cost per weight, or avoid the cost of high-purity refinement. For example, copper is added to the precious metal silver to make a more durable alloy for use in coins, housewares and jewelry. Coin silver, which was used for making silver coins in the past, contains 90% silver and 10% copper, by mass. Sterling silver contains 92.5% silver and 7.5% of other metals, usually copper, by mass.
The American Gold Eagle is an official gold bullion coin of the United States. Authorized under the Gold Bullion Coin Act of 1985, it was first released by the United States Mint in 1986. Because the term "eagle" also is the official United States designation for pre-1933 ten dollars gold coins, the weight of the bullion coin is typically used when describing American Gold Eagles to avoid confusion. This is particularly true with the 1/4-oz American Gold Eagle, which has a marked face value of ten dollars.
The American Platinum Eagle is the official platinum bullion coin of the United States. In 1995, Director of the United States Mint Philip N. Diehl, American Numismatic Association President David L. Ganz, and Platinum Guild International Executive Director Jacques Luben began the legislative process of creating the Platinum Eagle. After over two years of work, the 99.95% fine platinum coins were released by the United States Mint in 1⁄10, 1⁄4, 1⁄2 and 1 troy oz denominations. In late 2008, the fractional denominations were discontinued, leaving only the one ounce denomination. The Platinum Eagle is authorized by the United States Congress, and is backed by the United States Mint for weight, content, and purity.
The Canadian Gold Maple Leaf (GML) is a gold bullion coin that is issued annually by the Government of Canada. It is produced by the Royal Canadian Mint.
A bullion coin is a coin struck from precious metal and kept as a store of value or an investment rather than used in day-to-day commerce. A bullion coin is distinguished by an explicit statement of weight and fineness on the coin; this is because the weight and composition of coins intended for legal tender is specified in the coinage laws of the issuing nation, and therefore there is no need for an explicit statement on the coins themselves. The United Kingdom defines investment coins more specifically as coins that have been minted after 1800, have a purity of not less than 900 thousandths and are, or have been, legal tender in their country of origin. Under United States law, "coins" that fail the last of these requirements are not coins at all, and must be advertised as "rounds" instead. The American Eagle and Canadian Gold Maple Leaf series are the only coins available in gold, silver, platinum, and palladium.
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 400-troy-ounce Good Delivery gold bar. The kilobar, which is 1,000 grams 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. Asian markets differ in that they prefer gram gold bars as opposed to troy-ounce measurements. Popular sizes in the Asian region include 10 grams, 100 grams and 1,000 gram bars.
The Chinese Silver Panda is a series of silver bullion coins issued by the People's Republic of China. The design of the panda is changed every year and minted in different sizes and denominations, ranging from 0.5 troy oz. to 1 kilogram. Starting in 2016, Pandas switched to metric sizes. The 1 troy ounce coin was reduced to 30 grams, while the 5 troy ounce coin was reduced to 150 grams. There is also a Gold Panda series issued featuring the same designs as the Silver Panda coins.
Silver may be used as an investment like other precious metals. It has been regarded as a form of money and store of value for more than 4,000 years, although it lost its role as legal tender in developed countries when the use of the silver standard came to a final end in 1935. Some countries mint bullion and collector coins, however, such as the American Silver Eagle with nominal face values. In 2009, the main demand for silver was for industrial applications (40%), jewellery, bullion coins, and exchange-traded products. In 2011, the global silver reserves amounted to 530,000 tonnes.
The Canadian Silver Maple Leaf is a silver bullion coin that is issued annually by the Government of Canada. It is produced by the Royal Canadian Mint.
Junk silver is an informal term used in the United States, United Kingdom, Canada and Australia for any silver coin that is in fair or cull condition and has no numismatic or collectible value above the bullion value of the silver it contains. Such coins are popular among people seeking to invest in silver, particularly in small amounts. The word "junk" refers only to the value of the coins as collectibles and not to the actual condition of the coins; junk silver is not necessarily scrap silver.
The Canadian Platinum Maple Leaf is the official bullion platinum coin of Canada. First issued by the Royal Canadian Mint in 1988, it was available until 2002 in five different denominations, all of which are marked as containing .9995 pure platinum. The bullion coin was partly reintroduced in 2009 in the form of the 1 troy ounce denomination in .9999 purity, featuring a new portrait of Queen Elizabeth II on the obverse. The coins have legal tender status in Canada, but as is often the case with bullion coins, the face values of these coins is lower than the market price of the material they are made from.
The Coinage Act of 1965, Pub.L. 89–81, 79 Stat. 254, enacted July 23, 1965, eliminated silver from the circulating United States dime and quarter dollar coins. It also reduced the silver content of the half dollar from 90 percent to 40 percent; silver in the half dollar was subsequently eliminated by a 1970 law.
A gold coin is a coin that is made mostly or entirely of gold. Most gold coins minted since 1800 are 90–92% gold, while most of today's gold bullion coins are pure gold, such as the Britannia, Canadian Maple Leaf, and American Buffalo. Alloyed gold coins, like the American Gold Eagle and South African Krugerrand, are typically 91.7% gold by weight, with the remainder being silver and copper.
The Vienna Philharmonic, often shortened to Philharmonic, is a bullion coin of gold, silver, or platinum produced by the Austrian Mint. The coin is named for the Vienna Philharmonic orchestra, which inspired the design of both sides. It was introduced in 1989 as a one-troy ounce (ozt), gold coin with a face value of 2,000 Austrian schillings. It is generally one of the world's best selling bullion coins. In 2002, with the adoption of the euro currency, the nominal value of the one-ounce coin was changed to 100 euros. In 2008, the Mint introduced a one-ounce silver version of the coin with a nominal value of 1.50 euros. The silver coin is also one of the top selling bullion coins, ranked third in 2013. In 2016, the mint introduced a one ounce platinum coin with a face value of 100 euros.
