Thalaris
The Maria Theresa thaler (MTT) is a silver bullion coin and a type of Conventionsthaler that has been used in world trade continuously since it was first minted in 1741. It is named after Maria Theresa who ruled Austria, Hungary, and Bohemia from 1740 to 1780 and is depicted on the coin. History In 1741 the first MTT was struck according to the Reichsthaler standard with of a Cologne mark of fine silver, or 25.98 grams. In 1750 a new thaler was struck with a gross weight of of 1 Vienna mark of silver, fine (with a fine silver content of 23.39 grams, or of a Cologne mark). In 1751 this new standard Conventionsthaler was effectively adopted across the German-speaking world when it was accepted formally in the Bavarian monetary convention. This new, post-1751 thaler has continued as a trade coin ever since. Since the death of Maria Theresa in 1780, the coin has always been dated 1780. On 19 September 1857, Emperor Francis Joseph of Austria declared the Maria Theresa thaler ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Burgundian Cross
The Cross of Burgundy (french: Croix de Bourgogne; es, Cruz de Borgoña/Aspa de Borgoña; german: Burgunderkreuz; it, Croce di Borgogna; ca, Creu de Borgonya; nl, Bourgondisch kruis) is a saw-toothed ( raguly) form of the Cross of Saint Andrew, the patron saint of Burgundy, and a historical banner and battle flag used by holders of the title of Duke of Burgundy and their subjects. It was first used in the 15th century by the Valois Dukes of Burgundy, who ruled a large part of eastern France and the Low Countries as an effectively independent state. At the extinction of the Valois ducal line in 1477, the Burgundian Low Countries were inherited by the Habsburgs, who retained the title of Dukes of Burgundy and adopted the flag as one of the many symbols of their dynasty. After the Burgundian Habsburgs ascended to the throne of Spain in 1506, their officials introduced this ensign in the Spanish Empire throughout the Castilian and Aragonese territories in Europe and in the Amer ...

Saltire
A saltire, also called Saint Andrew's Cross or the crux decussata, is a heraldic symbol in the form of a diagonal cross, like the shape of the letter X in Roman type. The word comes from the Middle French ''sautoir'', Medieval Latin ''saltatoria'' (" stirrup"). From its use as field sign, the saltire came to be used in a number of flags, in the 16th century for Scotland and Burgundy, in the 18th century also as the ensign of the Russian Navy, and for Ireland. Notable 19th-century usage includes some of the flags of the Confederate States of America. It is also used in the flag of Jamaica and on seals, and as a heraldic charge in coats of arms. The term saltirewise or in saltire refers to heraldic charges arranged as a diagonal cross. The shield may also be divided per saltire, i.e. diagonally. A warning sign in the shape of a saltire is also used to indicate the point at which a railway line intersects a road at a level crossing. Heraldry and vexillology The saltire i ...

Millesimal Fineness
The fineness of a precious metal object (coin, bar, jewelry, etc.) 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. Various ways of expressing fineness have been used and two remain in common use: ''millesimal fineness'' expressed in units of parts per 1,000 and '' karats'' or ''carats'' used only for gold. Karats measure the parts per 24, so that 18 karat = = 75% and 24 karat gold is considered 100% g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Troy Weight
Troy weight is a system of Physical unit, units of mass that originated in 15th-century England, and is primarily used in the precious metals industry. The troy weight units are the Grain (unit), grain, the pennyweight (24 grains), the troy ounce (20 pennyweights), and the troy pound (12 troy ounces). The troy grain is equal to the grain unit of the Avoirdupois, avoirdupois system, but the troy ounce is heavier than the avoirdupois ounce, and the troy pound is lighter than the avoirdupois pound. One troy ounce (oz t) equals exactly 31.1034768 grams. Etymology Troy weight probably takes its name from the French market town of Troyes where English merchants traded at least as early as the early 9th century. The name ''troy'' is first attested in 1390, describing the weight of a platter, in an account of the travels in Europe of the Henry IV of England#Relationship with Richard II, Earl of Derby. Charles Moore Watson (1844–1916) proposes an alternative etymology: ''The Assize o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proof Coinage
Proof coinage refers to special early samples of a coin issue, historically made for checking the dies (as in demonstrating that something is true) and for archival purposes. Nowadays proofs are often struck in greater numbers specially for coin collectors (numismatists). Nearly all countries have issued proof coinage. Preparation of a proof striking usually involved polishing of the dies. They can usually be distinguished from normal circulation coins by their sharper rims and design, as well as much smoother "fields" – the blank areas not part of the coin's design. The dies for making modern proof coins are often treated with chemicals to make certain parts of the design take on a frosted appearance, with the polished fields taking on a mirror finish. Several other methods have been used in the past to achieve this effect, including sand blasting the dies, and matte proofs. Proof coins of the early 19th century even appear to be scratched, but it was part of the production ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austrian Mint
The Austrian Mint (german: Münze Österreich) is located in Vienna and is responsible for minting Austrian coins. Since 1989 it has been a public limited company (''Aktiengesellschaft'') and a subsidiary of Austria's central bank Oesterreichische Nationalbank, which also has its headquarters in Vienna.

Office Of Strategic Services
The Office of Strategic Services (OSS) was the intelligence agency of the United States during World War II. The OSS was formed as an agency of the Joint Chiefs of Staff (JCS) to coordinate espionage activities behind enemy lines for all branches of the United States Armed Forces.

Japanese Occupation Of Indonesia
The Empire of Japan occupied the Dutch East Indies (now Indonesia) during World War II from March 1942 until after the end of the war in September 1945. It was one of the most crucial and important periods in modern Indonesian history. In May 1940, Germany occupied the Netherlands, and martial law was declared in the Dutch East Indies. Following the failure of negotiations between the Dutch authorities and the Japanese, Japanese assets in the archipelago were frozen. The Dutch declared war on Japan following the 7 December 1941 Attack on Pearl Harbor. The Japanese invasion of the Dutch East Indies began on 10 January 1942, and the Imperial Japanese Army overran the entire colony in less than three months. The Dutch surrendered on 8 March. Initially, most Indonesians welcomed the Japanese as liberators from their Dutch colonial masters. The sentiment changed, however, as between 4 and 10 million Indonesians were recruited as forced labourers ('' romusha'') on economic dev ...
