Piatt Andrew, ''Quarterly Journal of Economics'', "The End of the Mexican Dollar", 18:3:321–356, 1904, p. 345 The first patterns of the yen based system were made from 1869 to 1870 as presentation pieces to the Emperor. The new currency system was eventually adopted by the Meiji period, Meiji government in an Act signed on June 27, 1871. Pattern coins are almost never released into circulation as they are made for evaluation purposes only.

Coin World
''Coin World'' is an American numismatic magazine, with weekly and monthly issues. It is among the world’s most popular non-academic publications for coin collectors and is covering the entire numismatic field, including coins, paper money, medals and tokens. Founding and early history (1960–1962) ''Coin World'' was founded as a weekly publication in 1960 by J. Oliver Amos, a seasoned publishing professional from the third generation of newspaper publishers. Amos took his experiences in producing the '' Sidney Daily News'' to the coin field, applying what he learned from printing ''Linn's Stamp News''. In 1960, the concept of a weekly coin publication was new. On the 25th anniversary of' ''Coin World'' in 1985, Amos related that he saw, "all the opportunities which could be developed from a weekly presentation – club meetings all over the country, personalities, and many other ideas that we had learned in publishing ''The Sidney Daily News'' as a community newspaper."

50 Sen Coin
The was a Japanese coin worth half of a Japanese yen, as 100 ''sen'' equalled 1 yen. These coins circulated from the late 19th century to the early 1950s, when Japan adopted a single currency unit and this coin was demonetized. History Meiji coinage (1870–1912) Fifty sen coins were first struck towards the end of 1870 (year 3 of Meiji) from a newly established mint at Osaka. These coins were likely not placed in circulation immediately, as they were officially adopted with twelve other denominations by the Meiji government in an act signed on June 27, 1871. This new coinage gave Japan a western style decimal system based on units of yen, which were broken down into subsidiary currency of sen, and rin. Fifty sen coins dated 1870 (year 3) were initially authorized to be struck in .800 silver, weighs 193 grains (12.51g), and has a 31.75mm diameter (1.25 in). The first design used is called , which had its features engraved by a commission of Japanese artists. This design fea ...

1 Yen Coin
The is the smallest denomination of the Japanese yen currency. Historically they were initially made of both silver and gold in the early 1870s. Issues facing the Japanese government at the time included wanting to adopt the gold standard, and competing against the Mexican dollar for use in foreign trade. The decision was made to use silver one yen coins exclusively outside of Japan for trade, while gold coins were minted and used in mainland Japan. Gold and silver coins were eventually allowed to co-circulate in mainland Japan from 1878 to 1897 when they were demonetized. Millions of former one yen silver coins were countermarked by the Japanese government for use outside of the mainland. Silver one yen coins continued to be minted until 1914 for backing up currency. One yen coins were not made again until after World War II in the late 1940s for a brief period of time. The current one yen coin design was first minted in 1955, is made up of pure aluminum, and has a young tree d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Taishō Era
The was a period in the history of Japan dating from 30 July 1912 to 25 December 1926, coinciding with the reign of Emperor Taishō. The new emperor was a sickly man, which prompted the shift in political power from the old oligarchic group of elder statesmen (or ) to the Imperial Diet of Japan and the democratic parties. Thus, the era is considered the time of the liberal movement known as Taishō Democracy; it is usually distinguished from the preceding chaotic Meiji era and the following militaristic-driven first part of the Shōwa era. Etymology The two kanji characters in Taishō () were from a passage of the Classical Chinese ''I Ching'': (translated: "Great prevalence is achieved through rectitude, and this is the Dao of Heaven.") The term could be roughly understood as meaning "great rectitude", or "great righteousness". Meiji legacy On 30 July 1912, Emperor Meiji died and Crown Prince Yoshihito succeeded to the throne as Emperor of Japan. In his coron ...

10 Sen Coin
The was a Japanese coin worth one tenth of a Japanese yen, as 100 ''sen'' equalled 1 yen. These coins were minted from the late 19th century up until the end of World War II. History Meiji coinage (1870–1912) Ten sen coins were first struck towards the end of 1870 (year 3 of Meiji) from a newly established mint at Osaka. Initially, this process was done by engineers from the United Kingdom as Japan did not have the technology or raw materials to manufacture new coins. Authorization was given to strike ten sen coins in .800 silver, weighs 38.6 grains (2.5g), and has a 18.28mm diameter (0.72 in). The first design used is nicknamed , which had its features engraved by a commission of Japanese artists. The obverse side features a dragon with an open mouth, while on the reverse there is a paulownia decoration with a sunburst in the center, and the chrysanthemum seal up on top. While dated 1870 (year 3), these first year ten sen coins were not released into circulation until the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
5 Sen Coin
The was a Japanese coin worth one twentieth of a Japanese yen, as 100 ''sen'' equalled 1 yen. These coins were minted from the late 19th century until the end of World War II. Like the other denominations of sen, these coins were eventually taken out of circulation at the end of 1953. While not in circulation any more, these coins are bought and sold by numismatists for academic study, and by those with a hobby. History Meiji coinage (1870–1906) Five sen coins were first struck towards the end of 1870 from a newly established mint in Osaka. They were then held at the mint until the following year of issuance when they circulated alongside newly minted 1871 (year 4) dated coins. Five sen coins along with twelve other denominations were adopted by the Meiji government in an act signed on June 27, 1871. This new coinage gave Japan a western style decimal system based on units of yen, which were broken down into subsidiary currency of sen, and rin. Five sen coins dated 1870 and 1 ...

Proof Coinage
Proof coinage refers to special early samples of a coin issue, historically made for checking the die (manufacturing), dies (as in demonstrating that something is true) and for archival purposes. In modern times, proofs are often struck in greater numbers, especially for coin collecting, 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 b ...

1 Sen Coin
The was a Japanese coin worth one-hundredth of a Japanese yen, as 100 ''sen'' equalled 1 yen. One sen coins were first struck for circulation during the 6th year of Meiji's reign (1873) using a dragon design. The denomination had been adopted in 1871 but coinage at the time could not be carried out. Aside from an alloy change and a new rice stalk wreath design, one sen coins remained the same weight and size for the remainder of the era. The situation changed when World War I broke out under Emperor Taishō as rising metal costs led to a size and weight reduction. These smaller coins were first produced in 1916 with a paulownia design which was seen as liberal at the time. Emperor Shōwa took the throne in 1926, and Japan was pushed into a militaristic regime by the early 1930s causing metals to be set aside for wartime conditions. These effects would later impact one sen coins through numerous alloy, size, and design changes. Bronze was the first alloy to be used for coinage ...

Half Sen Coin
The was a Japanese coin worth one two-hundredth of a Japanese yen, as 100 ''sen'' equalled 1 yen. All half sen coins were minted during the Meiji period between 1873 and 1888, and are made from nearly pure copper. These coins were later replaced for a brief time by 5 rin coin, another coin with the same value in the 1910s. The half sen coin was demonetized at the end of 1953 along with other subsidiary coinage and is no longer legal tender. They are now readily available for collectors to own as coins from this denomination were minted in large quantities. History Half sen coins along with twelve other denominations were adopted by the Meiji period, Meiji government in an act signed on June 27, 1871. This new coinage gave Japan a western style decimal system which was based on units of yen, sen, and rin. Each half sen coin was authorized to weigh 55 grains (3.56 g) struck in a copper alloy. The first coins minted are dated 1870 (year 3), but these were intended as trial strikes o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Government Seal Of Japan
The Government Seal of Japan, one of the country's national seals, is the emblem ''( mon)'' of paulownia used by the Prime Minister, the Cabinet and the executive branch of the Government of Japan on official documents. It is generally known as the , used by those in power and is the official emblem of the Japanese government today. It resembles a stylized paulownia with 5-7-5 flowers. It is one of various paulownia ''mon'', collectively known as the or the . History Before the Chrysanthemum Seal was used extensively, the Paulownia Seal originally was the private symbol of the Japanese Imperial Family, from as early as the sixteenth century. The Toyotomi clan, led by Toyotomi Hideyoshi, later adopted the Paulownia Seal for use as the crest of his clan. After the Meiji Restoration, the seal was eventually adopted as the emblem of the Japanese government. It is now mainly used by the Japanese government, as a contrast to the Chrysanthemum Seal which represents the Empero ...
