Jean Boisard
Jean Boisard (also Boizard) was a learned Frenchman, who died around 1725. His birth date is not known. He is considered to be one of founders, in the 17th century, of numismatics, the science or specialized knowledge and collection of medals and coins. He was Counsellor at the French royal “ Cour des Monnaies”. In 1692, he published a short treatise on coins, entitled “Traité des Monnaies, de leurs circonstances et dépendances”. In his book (which was reprinted several times during the first quarter of the 18th century), very precise and accurate details were given on alloy and on manufacturing secrets. As a result, the government forbade its circulation, being afraid that it could be used as a guidebook for counterfeit A counterfeit is a fake or unauthorized replica of a genuine product, such as money, documents, designer items, or other valuable goods.

Numismatics
Numismatics is the study or collection of currency, including coins, tokens, paper money, medals, and related objects. Specialists, known as numismatists, are often characterized as students or collectors of coins, but the discipline also includes the broader study of money and other means of payment used to resolve debts and exchange good (economics), goods. The earliest forms of money used by people are categorised by collectors as "odd and curious", but the use of other goods in barter exchange is excluded, even where used as a circulating currency (e.g., cigarettes or instant noodles in prison). As an example, the Kyrgyz people used horses as the principal currency unit, and gave small change in sheepskin, lambskins; the lambskins may be suitable for numismatic study, but the horses are not. Many objects have been used for centuries, such as Cowry, cowry shells, precious metals, Cocoa beans#History, cocoa beans, Rai stones, large stones, and Gemstone, gems. Etymology Firs ...

Treatise
A treatise is a Formality, formal and systematic written discourse on some subject concerned with investigating or exposing the main principles of the subject and its conclusions."mwod:treatise, Treatise." Merriam-Webster Online Dictionary. Accessed September 12, 2020. A ''monograph'' is a treatise on a specialized topic. Etymology The word "treatise" has its origins in the early 14th century, derived from the Anglo-French term ''tretiz'', which itself comes from the Old French ''traitis'', meaning "treatise" or "account." This Old French term is rooted in the verb ''traitier'', which means "to deal with" or "to set forth in speech or writing". The etymological lineage can be traced further back to the Latin word ''tractatus'', which is a form of the verb ''tractare'', meaning "to handle," "to manage," or "to deal with". The Latin roots suggest a connotation of engaging with or discussing a subject in depth, which aligns with the modern understanding of a treatise as a formal ...

Alloy
An alloy is a mixture of chemical elements of which in most cases at least one is a metal, metallic element, although it is also sometimes used for mixtures of elements; herein only metallic alloys are described. Metallic alloys often have properties that differ from those of the pure elements from which they are made. The vast majority of metals used for commercial purposes are alloyed to improve their properties or behavior, such as increased strength, hardness or corrosion resistance. Metals may also be alloyed to reduce their overall cost, for instance alloys of gold and Copper(II) sulfate, copper. A typical example of an alloy is SAE 304 stainless steel, 304 grade stainless steel which is commonly used for kitchen utensils, pans, knives and forks. Sometime also known as 18/8, it as an alloy consisting broadly of 74% iron, 18% chromium and 8% nickel. The chromium and nickel alloying elements add strength and hardness to the majority iron element, but their main function is ...

Counterfeit
A counterfeit is a fake or unauthorized replica of a genuine product, such as money, documents, designer items, or other valuable goods. Counterfeiting generally involves creating an imitation of a genuine item that closely resembles the original to deceive others into believing it is authentic. Counterfeit products are often made to take advantage of the higher value of the original product, typically using lower-quality materials or production methods. Counterfeit food, drinks, medicines, and personal care products can contain harmful or inactive ingredients, causing anything from mild issues to serious, life-threatening ones. Counterfeit footwear, clothing, and accessories have been found to contain high levels of lead, arsenic, and phthalates. Forgery of money or government bonds Counterfeit money is currency that is produced without the legal sanction of the state or government; this is a crime in all jurisdictions of the world.

Year Of Death Missing
A year is a unit of time based on how long it takes the Earth to orbit the Sun. In scientific use, the tropical year (approximately 365 solar days, 5 hours, 48 minutes, 45 seconds) and the sidereal year (about 20 minutes longer) are more exact. The modern calendar year, as reckoned according to the Gregorian calendar, approximates the tropical year by using a system of leap years. The term 'year' is also used to indicate other periods of roughly similar duration, such as the lunar year (a roughly 354-day cycle of twelve of the Moon's phasessee lunar calendar), as well as periods loosely associated with the calendar or astronomical year, such as the seasonal year, the fiscal year, the academic year, etc. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by changes in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
