United States Mint Coin Sets
The United States Mint has released annual collections of coins most years since 1936. United States Mint 50 State Quarters Proof Set With the launch of the 50 State Quarters Program in 1999, the Mint began marketing proof sets of just the five quarters released in the given year. These sets are essentially a reduced version of the regular issue proof sets and the packaging maintained the same blue color scheme, but came in a smaller box and different certificate of authenticity. This collection ceased with the resolution of the program in 2008. These sets are usually denoted as the ''5-piece'' sets from a given year. All issues were produced at the San Francisco Mint. United States Mint 50 State Quarters Silver Proof Set The 50 State Quarters Proof Sets produced with the five quarters produced that year in 90% silver and again were the same as the year's Silver Proof Set but in a reduced red packaging and unique certificate of authenticity. All issues were produced at the San Fra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Mint
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. It does not produce paper money; that responsibility belongs to the Bureau of Engraving and Printing. 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. History The Massachusetts Bay Colony established a mint in Boston in 1652. John Hull was Treasurer and mintmaster; Hull's partner at the "Hull Mint" was Robert Sanderson. The historical marker reads: The first authorization for the establishment of a mint in the United States was in a resolution of the Congress of the Confederation of February 21, 1782, and the first general-circulation coin of the United Stat ...

Nickel (U
Nickel is a chemical element with Chemical symbol, symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and Ductility, ductile transition metal. Pure nickel is chemically reactive but large pieces are slow to react with air under Standard conditions for temperature and pressure, standard conditions because a Passivation (chemistry), passivation layer of Nickel(II) oxide, nickel oxide forms on the surface that prevents further corrosion. Even so, pure native metal, native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger iron meteorite, nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric iron, Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer core, Eart ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver
Silver is a chemical element with the symbol Ag (from the Latin ', derived from the Proto-Indo-European ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures.

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 onwa ... [...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 ...

Presidential Dollar Coin Program
Presidential dollar coins (authorized by ) are a series of United States dollar coins with engravings of relief portraits of U.S. presidents on the obverse and the Statue of Liberty (''Liberty Enlightening the World'') on the reverse. From 2007 to 2011, Presidential dollar coins were minted for circulation in large numbers, resulting in a large stockpile of unused $1 coins. From 2012 to 2016, new coins in the series were minted only for collectors. A new coin was released on December 4, 2020, to honor George H. W. Bush, who died after the original program ended. Legislative history , the Presidential $1 Coin Act of 2005, was introduced on May 17, 2005, by Senator John E. Sununu with over 70 co-sponsors. It was reported favorably out of the U.S. Senate Committee on Banking, Housing, and Urban Affairs without amendment on July 29, 2005. The Senate passed it with a technical amendment (), by unanimous consent on November 18, 2005. The House of Representatives passed it (291-113) ...

United States Bicentennial Coinage
The United States Bicentennial coinage is a set of circulating commemorative coins, consisting of a quarter, half dollar and dollar struck by the United States Mint in 1975 and 1976. Regardless of when struck, each coin bears the double date 1776–1976 on the normal obverses for the Washington quarter, Kennedy half dollar and Eisenhower dollar. No coins dated 1975 of any of the three denominations were minted. Given past abuses in the system, the Mint advocated against the issuance of commemorative coins starting in the 1950s. Beginning in 1971, members of Congress introduced bills to authorize coins to honor the United States Bicentennial, which would occur in 1976. The Mint, through its director, Mary Brooks, initially opposed such proposals, but later supported them, and Congress passed legislation requiring the temporary redesign of the reverse of the quarter, half dollar and dollar. A nationwide competition resulted in designs of a Colonial drummer for the qu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eisenhower Dollar
The Eisenhower dollar was a one-dollar coin issued by the United States Mint from 1971 to 1978; it was the first coin of that denomination issued by the Mint since the Peace dollar series ended in 1935. The coin depicts President Dwight D. Eisenhower on the obverse, and on the reverse a stylized image honoring the 1969 Apollo 11 Moon mission based on the mission patch designed by astronaut Michael Collins. Both sides were designed by Frank Gasparro. It is the only large-size U.S. dollar coin whose circulation strikes contained no silver. In 1965, because of rises in bullion prices, the Mint began to strike copper-nickel clad coins instead of silver. No dollar coins had been issued in thirty years, but, beginning in 1969, legislators sought to reintroduce a dollar coin into commerce. After Eisenhower died that March, there were a number of proposals to honor him with the new coin. While these bills generally commanded wide support, enactment was delayed by a dispute over whet ...

Philadelphia Mint
The Philadelphia Mint in Philadelphia was created from the need to establish a national identity and the needs of commerce in the United States. This led the Founding Fathers of the United States to make an establishment of a continental national mint, a main priority after the ratification of the Constitution of the United States. The Coinage Act of 1792 was entered into law on April 2. It proclaimed the creation of the United States Mint. Philadelphia at that time was the nation's capital; therefore the first mint facility was built there. The Coinage Act of 1792 also instituted a decimal system based on a dollar unit; specified weights, metallic composition and fineness; and required each United States coin feature "an impression emblematic of liberty". History First building (1792–1833) David Rittenhouse, an American scientist, was appointed the first director of the mint by President George Washington. Two lots were purchased by Rittenhouse on July 18, 1792, at Seve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Half Dollar (U
The term "half dollar" refers to a half-unit of several currencies that are named "dollar". One dollar ( $1) is normally divided into subsidiary currency of 100 cents, so a half dollar is equal to 50 cents. These half dollars (aka 50 cent pieces) are denominated as either Coins or as banknote A banknote—also called a bill (North American English), paper money, or simply a note—is a type of negotiable instrument, negotiable promissory note, made by a bank or other licensed authority, payable to the bearer on demand. Banknotes w ...s. Although more than a dozen countries have their own unique dollar currency, not all of them use a 50 cent piece or half dollar.
