The United States Mint is a bureau of the Department of the Treasury responsible for producing coinage for the United States to conduct its trade and commerce, as well as controlling the movement of bullion. The U.S. Mint is one of two U.S. agencies that produce money in the case of minting coinage; the other is the Bureau of Engraving and Printing, which prints paper currency. The first United States Mint was created in Philadelphia in 1792, and soon joined by other centers, whose coins were identified by their own mint marks. There are currently four active coin-producing mints: Philadelphia, Denver, San Francisco, and West Point.
A double eagle is a gold coin of the United States with a denomination of $20. The coins are 34 mm × 2 mm and are made from a 90% gold and 10% copper alloy and have a total weight of 1.0750 troy ounces.
The United States three cent piece was a unit of currency equaling 3⁄100 of a United States dollar. The mint produced two different three-cent coins for circulation: the three-cent silver and the three-cent nickel. Additionally, a three-cent bronze coin was made as a pattern in 1863. During the period from 1865 to 1873, both coins were minted, albeit in very small quantities for the silver three-cent piece.
The Indian Head cent, also known as an Indian Head penny, was a one-cent coin ($0.01) produced by the United States Bureau of the Mint from 1859 to 1909. It was designed by James Barton Longacre, the Chief Engraver at the Philadelphia Mint.
A key date is a term used in coin collecting and it refers to a date of a given coin series or coin set that is harder to obtain than other dates in the series. A key date coin is usually one with a lower mintage total and it is more valuable than others in the series. Many coin collectors collect coins to fill out a complete set of a series.
The 10 yen coin is one denomination of the Japanese yen.
The three-dollar piece was a gold coin produced by the United States Bureau of the Mint from 1854 to 1889. Authorized by the Act of February 21, 1853, the coin was designed by Mint Chief Engraver James B. Longacre. The obverse bears a representation of Lady Liberty wearing a headdress of a Native American princess and the reverse a wreath of corn, wheat, cotton, and tobacco.
The gold dollar or gold one-dollar piece is a gold coin that was struck as a regular issue by the United States Bureau of the Mint from 1849 to 1889. The coin had three types over its lifetime, all designed by Mint Chief Engraver James B. Longacre. The Type 1 issue has the smallest diameter of any United States coin minted to date.
First strike is a marketing term used by third party coin grading services which refers to coins which were struck first by a mint. The U.S. Mint maintains that there is no widely accepted and standardized numismatic industry definition of First Strike coins. Several coin grading companies have decided that a "first strike" coin is one that shipped from the mint in the first month of the new minting.
A type set is a coin collection based on coin design or type. Traditional collections consist of all dates within a series such as state quarters or Lincoln cent.
The 1-yen coin is the smallest denomination of the Japanese yen currency. Historically they were initially made of both silver and gold in the early 1870s. Issues facing the Japanese government at the time included wanting to adopt the gold standard, and competing against the Mexican dollar for use in foreign trade. The decision was made to use silver one yen coins exclusively outside of Japan for trade, while gold coins were minted and used in mainland Japan. Gold and silver coins were eventually allowed to co-circulate in mainland Japan from 1878 to 1897 when they were demonetized. Millions of former one yen silver coins were countermarked by the Japanese government for use outside of the mainland. Silver one yen coins continued to be minted until 1914 for backing up currency.
The three-cent silver, also known as the three-cent piece in silver or trime, was struck by the Mint of the United States for circulation from 1851 to 1872, and as a proof coin in 1873. Designed by the Mint's chief engraver, James B. Longacre, it circulated well while other silver coinage was being hoarded and melted, but once that problem was addressed, became less used. It was abolished by Congress with the Coinage Act of 1873.
Michael "Miles" Standish was an American businessman, author, rare coin expert, sports memorabilia expert and philanthropist. He was a co-founder of Collectors Universe and served as vice president of the Numismatic Guaranty Corporation (NGC).
The Saddle Ridge Hoard is the name given to a hoard of 1,427 gold coins unearthed in the Gold Country of the Sierra Nevada, California in 2013. The face value of the coins totaled $27,980, but was assessed to be worth $10 million. The hoard contains $27,460 in twenty-dollar coins, $500 in ten-dollar coins, and $20 in five-dollar coins, all dating from 1847 to 1894. The collection is the largest known discovery of buried gold coins that has ever been recovered in the United States.
A coin set, or mint set, is a collection of Uncirculated or Proof coins, released by a mint. Such sets are usually released annually and often called a year set. They include sets of all the circulating coins of that year, as well as sets of commemorative coins.
The 20 yen coin (二十圓硬貨) was a denomination of Japanese yen. These coins were minted in gold, and during their lifespan were the highest denomination of coin that circulated in the country. The first coins were minted in 1870 following the introduction of a decimal currency system. Twenty Yen coins spanned three different Imperial eras before mintage was halted in 1932. Many of these coins were then melted or destroyed as a result of the wars between 1931 and 1945. These coins are now collected by numismatists for academic study, and by those with a hobby.
The 2 yen coin (二圓金貨) was a short lived denomination of Japanese yen. During the first year of mintage in 1870, hundreds of thousands of these new coins were struck. These figures dropped off sharply as the Japanese government looked towards silver as a trading commodity. The supply of gold bullion had also dwindled causing the demand for these coins to outpace the supply available. The public hoarded two yen coins along with other denominations of gold causing them not to circulate during the mid 1870s. Japan eventually obtained a supply of gold bullion towards the end of the century, but this came too late for the two yen coin which was last minted in 1892. Almost one hundred years later the two yen coin was officially demonetized. While not in circulation any more, these coins are bought and sold by numismatics for academic study, and by those with a hobby.
The Binion Hoard was American gambling executive Ted Binion's collection of silver and silver dollars. Binion had a safe installed 12 ft (3.7 m) deep in the ground of a vacant lot that he owned in Pahrump, Nevada, United States. In the safe he stored his 46,000 pounds (21,000 kg) of silver, including 135,000 silver dollars. In 1998, Binion died of an overdose and authorities determined that he had been murdered. Two days after his death Richard Tabish and four other people were arrested for digging up the buried silver.
The 1893-S Morgan dollar is a United States dollar coin struck in 1893 at the San Francisco Mint. It is the lowest mintage business strike Morgan dollar in the series. The 1893-S is considered to be a key date in the Morgan dollar series: examples of the coin in both mint state and in circulated condition are valuable.
