During the mid 1500's the Manchurians rebelled against the Ming Dynasty, and in AD 1559 Nurhachu (also know as T'ai Tsu) established a small Manchu dynasty.By 1625 Nurhachu has gained enough territory to need a capital, which he established at Mukden, but he died only a year later which brought his son Abahay (also known as T'ai Tsung) to the throne.There are additional Japanese symbols for larger multiples of 10: 100: 百 1000: 千 The Japanese number-writing system is known as a non-positional numeral system because individual symbols don't identify their value strictly based on their position in the number.For example, 40 (四十, 4 10), 400 (四百, 4 100), and 4000 (四千, 4 1000) all use exactly 2 symbols in Japanese (while the Arabic numbers 40, 400, and 4000 use 2, 3, and 4 respectively). This practice largely stopped after World War 2, and for most purposes Japan uses the same year as America would use.Instead, Japanese uses combinations of numerals which add and/or multiply to the number being written.For example, 11 is not written 一一 (1 1) - it is 十一 (10 1, or 10 1). 20 is 二十 (2 10, or 2 * 10), and 22 is 二十二 (2 10 2, or 2 * 10 2).That information, along with the coin's country, is the minimum you'd need to look up the coin in a guide, check if it's in your collection, or trade with another collector.The Chinese Numerals Japanese is one such language which doesn't use Arabic numerals (0, 1, 2...).
After those numerals no year symbol (年) should be entered. There are some examples of how the year is inscribed on the coins.All three coins remain common today due to the quantity struck.Circulation pieces were in copper nickel; Congress also mandated 45,000,000 part-silver pieces be struck for collectors.Denominations are written in "financial" Chinese numerals.Taiwan is an island nation east of China and south of Japan. Its official name is the Republic of China (ROC), as the result of the Chinese Civil War which led to a communist victory in the mainland forming the People's Republic of China, with the Republican forces retreating to Taiwan.Abahay changed the Dynastic name to Ch'ing in 1638 and on his death in 1644 his nine year old son Shih Tsu (know as Shun Chih) came to the throne.
