Petition Crown
The Petition Crown was a pattern coin produced in 1663 by Thomas Simon, a celebrated English medallist and coin-designer. The coin was submitted directly by the artist to King Charles II as a personal 'petition' against the contemporary coins designed by the Flemish brothers John and Joseph Roettiers, and for the further Royal consideration that only Simon's designs be used for all future specie now that machine-made currency had been adopted universally for the production of British coinage. The rivalry between the Roettiers brothers and Thomas Simon resulted from a Royal competition to design this new milled coinage. For unclear reasons, Simon did not submit his trial design in time, resulting in the Flemish engravers winning by default and their coinage being issued for circulation in 1662. However Simon's desire to win back the King's affections resulted in the development of this trial piece the following year. Not only did it dramatically differ from the coins produced by ...

The Petition Crown
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun ''thee'' ...

Sheldon Coin Grading Scale
The Sheldon Coin Grading Scale is a 70-point coin grading scale used in the numismatic assessment of a coin's quality. The American Numismatic Association based its ''Official ANA Grading Standards'' in large part on the Sheldon scale. The scale was created by William Herbert Sheldon. Original Sheldon Scale (1949) In 1949, the original scale was first presented in Dr. William H. Sheldon's ''Early American Cents, 1793–1814'' titled "A Quantitative Scale for condition" as a way to grade Large cent (United States coin), Large cents. The scale is known today as the Sheldon scale. Adapted scale (1970s–present) By 1953 the original Sheldon scale had become outdated. It was not until the 1970s, however, that the American Numismatic Association, ANA chose to adapt the scale for use on all US coins. The scale used today is a modification of the original Sheldon scale, with added adjustments, additions, deletions, and modifications to it. ''Note'': Some early American coin varieti ...

Electrotyping
Electrotyping (also galvanoplasty) is a chemical method for forming metal parts that exactly reproduce a model. The method was invented by a Prussian engineer Moritz von Jacobi in Russia in 1838, and was immediately adopted for applications in printing and several other fields. As described in an 1890 treatise, electrotyping produces "an exact facsimile of any object having an irregular surface, whether it be an engraved steel- or copper-plate, a wood-cut, or a form of set-up type, to be used for printing; or a medal, medallion, statue, bust, or even a natural object, for art purposes." In art, several important "bronze" sculptures created in the 19th century are actually electrotyped copper, and not bronze at all; sculptures were executed using electrotyping at least into the 1930s. In printing, electrotyping had become a standard method for producing plates for letterpress printing by the late 1800s. It complemented the older technology of stereotyping, which involved me ...

Numismatist
A numismatist is a specialist, researcher, and/or well-informed collector of numismatics, numismatics/coins ("of coins"; from Late Latin , genitive of ). Numismatists can include collectors, specialist dealers, and scholar-researchers who use coins (and possibly, other currency) in object-based research. Although use of the term ''numismatics'' was first recorded in English in 1799, people had been collecting and studying coins long before then all over the world. (The branch of numismatics that deals with the study and collection of paper currency and banknotes by notaphilists is called Notaphily) Numismatist collectors This group chiefly may derive pleasure from the simple ownership of monetary devices and studying these coins as private amateur scholars. In the classical field, amateur collector studies have achieved quite remarkable progress in the field. Examples include Walter Breen, a noted numismatist who was not an avid collector, and King Farouk I of Egypt, an avid col ...

Obverse And Reverse
The obverse and reverse are the two flat faces of coins and some other two-sided objects, including paper money, flags, seals, medals, drawings, old master prints and other works of art, and printed fabrics. In this usage, ''obverse'' means the front face of the object and ''reverse'' means the back face. The obverse of a coin is commonly called ''heads'', because it often depicts the head of a prominent person, and the reverse ''tails''. In numismatics, the abbreviation ''obv.'' is used for ''obverse'',David Sear. ''Greek Imperial Coins and Their Values.'' Spink Books, 1982. p. xxxv. while , )(Jonathan Edwards.
