Kings Norton Metal Company
Kings Norton Mint was a 19th-century metalworking and minting company founded in Birmingham, England. As a private company it worked to develop and manufacture various metal products including wire, nails, ammunitions and later coins on behalf of the Royal Mint. Notably it is credited with inventing solid-drawn ammunition cartridges for small firearms. History The Kings Norton Mint was founded in 1889 as ''The King's Norton Metal Company'' by engineers Thomas Richard Bayliss and George Hagger. Initially the company specialised in the manufacture of coinage strip and coin blanks however also produces products for the construction industry. Prior to the mint's creation the nearby Birmingham Mint under the ownership of Ralph Heaton III had dominated the industry little competition in competing for minting contract. By 1912 the company acquired a contract from the Royal Mint to supply bronze Planchet for its London based facility and later started to supply coinage for the B ...

Metallurgy
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys. Metallurgy encompasses both the science and the technology of metals; that is, the way in which science is applied to the production of metals, and the engineering of metal components used in products for both consumers and manufacturers. Metallurgy is distinct from the craft of metalworking. Metalworking relies on metallurgy in a similar manner to how medicine relies on medical science for technical advancement. A specialist practitioner of metallurgy is known as a metallurgist. The science of metallurgy is further subdivided into two broad categories: chemical metallurgy and physical metallurgy. Chemical metallurgy is chiefly concerned with the reduction and oxidation of metals, and the chemical performance of metals. Subjects of study in chemical metallurgy include mi ...

Mint (facility)
A mint is an industrial facility which manufactures coins that can be used as currency. The history of mints correlates closely with the history of coins. In the beginning, hammered coinage or cast coinage were the chief means of coin minting, with resulting production runs numbering as little as the hundreds or thousands. In modern mints, coin dies are manufactured in large numbers and planchets are made into milled coins by the billions. With the mass production of currency, the production cost is weighed when minting coins. For example, it costs the United States Mint much less than 25 cents to make a quarter (a 25 cent coin), and the difference in production cost and face value (called seigniorage) helps fund the minting body. Conversely, a U.S. penny ($0.01) cost $0.015 to make in 2016. History The first minted coins The earliest metallic money did not consist of coins, but of unminted metal in the form of rings and other ornaments or of weapons, which were used for th ...

Metalworking
Metalworking is the process of shaping and reshaping metals to create useful objects, parts, assemblies, and large scale structures. As a term it covers a wide and diverse range of processes, skills, and tools for producing objects on every scale: from huge ships, buildings, and bridges down to precise engine parts and delicate jewelry. The historical roots of metalworking predate recorded history; its use spans cultures, civilizations and millennia. It has evolved from shaping soft, native metals like gold with simple hand tools, through the smelting of ores and hot forging of harder metals like iron, up to highly technical modern processes such as machining and welding. It has been used as an industry, a driver of trade, individual hobbies, and in the creation of art; it can be regarded as both a science and a craft. Modern metalworking processes, though diverse and specialized, can be categorized into one of three broad areas known as forming, cutting, or joining processes. Mo ...

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

Royal Mint
The Royal Mint is the United Kingdom's oldest company and the official maker of British coins. Operating under the legal name The Royal Mint Limited, it is a limited company that is wholly owned by His Majesty's Treasury and is under an exclusive contract to supply the nation's coinage. As well as minting circulating coins for the UK and international markets, The Royal Mint is a leading provider of precious metal products. The Royal Mint was historically part of a series of mints that became centralised to produce coins for the Kingdom of England, all of Great Britain, the United Kingdom, and nations across the Commonwealth. The Royal Mint operated within the Tower of London for several hundred years before moving to what is now called Royal Mint Court, where it remained until the 1960s. As Britain followed the rest of the world in decimalising its currency, the Mint moved from London to a new 38-acre (15 ha) plant in Llantrisant, Glamorgan, Wales, where it has remained sin ...

Cartridge (firearms)
A cartridge or a round is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (usually either smokeless powder or black powder) and an ignition device (primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for the practical purpose of convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often informally used to refer to a complete cartridge, it is correctly used only to refer to the projectile. Cartridges can be categorized by the type of their primers – a small charge of an impact- or electric-sensitive chemical mixture that is located: at the center of the case head (centerfire); inside the rim ( rimfire); inside the walls on the fold of the case base that is shaped like a cup (cupfire, now obsolete); in a sideways projection that is shaped like a pin (pinfire, now obsolete); or a ...

Birmingham Mint
The Birmingham Mint was a coining mint and metal-working company based in Birmingham, England. Formerly the world's largest privately-owned mint, the company produced coins for many foreign nations including France, Italy, China, and much of the British Empire during the 19th century. Beginning life in 1817 as a family-run brass fittings maker, the company later purchased equipment from the defunct Soho Mint to begin its own coin production. Over the subsequent decades the mint won contracts to mint national currencies, and built minting facilities worldwide so that at its height the Birmingham Mint's capacity surpassed that of even the Royal Mint. By the early 2000s disagreement with the Royal Mint over foreign contracts led to a slump in sales, cumulating in the mint's eventual closure in 2003 ending its almost 200-year history. According to Companies House, however, as of 2021 a revived mint continues to operate, albeit with little business activity. History 18th-19th c ...

Planchet
A planchet is a round metal disk that is ready to be struck as a coin. An older word for planchet is flan. They are also referred to as blanks. History The preparation of the flan or planchet has varied over the years. In ancient times, the flan was heated before striking because the metal that the coin dies were made of was not as hard as dies today, and the dies would have worn faster and broken sooner had the flan not been heated to a high temperature to soften it. An unusual method was used to mint the one-sided, bowl-shaped ''pfennigs'' of the Holy Roman Empire. The planchet used for these so-called ''Schüsselpfennigs'' was larger than the coin die itself. The coins were made by striking with only one upper die on the larger planchet. As a result, the perimeter of the planchet was pressed upwards in the shape of a bowl or plate. Until the 18th century they were minted mainly in the Harz Mountains. The curved shape of the pfennig was very useful for handling small change ...

British Empire
The British Empire was composed of the dominions, colonies, protectorates, mandates, and other territories ruled or administered by the United Kingdom and its predecessor states. It began with the overseas possessions and trading posts established by England between the late 16th and early 18th centuries. At its height it was the largest empire in history and, for over a century, was the foremost global power. By 1913, the British Empire held sway over 412 million people, of the world population at the time, and by 1920, it covered , of the Earth's total land area. As a result, its constitutional, legal, linguistic, and cultural legacy is widespread. At the peak of its power, it was described as "the empire on which the sun never sets", as the Sun was always shining on at least one of its territories. During the Age of Discovery in the 15th and 16th centuries, Portugal and Spain pioneered European exploration of the globe, and in the process established large overse ...

Mint Mark
A mint mark is a letter, symbol or an inscription on a coin indicating the mint where the coin was produced. It should not be confused with a mintmaster mark which is the mark of the mintmaster. History Mint marks were first developed to locate a problem. If a coin was underweight, or overweight, the mint mark would immediately tell where the coin was minted, and the problem could be located and fixed. Another problem which could occur would be a dishonest mint official debasing the coin, or putting less precious metal in the coin than specified. The first mint marks, called "Magistrate Marks" were developed by the Greeks, and named the Magistrate in charge of producing that coin. Debasing a coin, or otherwise tampering with it, was a very serious crime, often punishable by death in many civilizations. For example, in 1649, the directors of the Spanish colonial American Mint at Potosi, in what is today Bolivia, were condemned to death for seriously debasing the coinage. The init ...
