Re: Large coin, possibly Chinese, possibly silver
In 1932 The Republic of China minted 2,250,000 Silver (.7555 actual silver weight) dollars with a bust of Sun Yat-sen facing left on the obverse and a junk (Chinese boat) on the reverse. Also, on the reverse, above the junk are three flying birds and, a rising sun with rays, is on the right.
The date on the coin, in Chinese, is 21 for year 21. In China the year of the coin was depicted by the number of years the ruler was in power. i.e., Sun Yat-sen ruled for 23 years so coins minted during years 21, 22 and 23 carry the Chinese character for year 21, year 22 and 23.
In year 22 (1933), 46,400,000 junk silver (same actual silver weight as year 21) dollars were minted with the same obverse, but the reverse was minus the flying birds and the rising sun.
In year 23 (1934) 128,740,000 junk dollars were minted with the same criteria as year 22.
These junk dollars proved to be such a popular form of exchange around the provinces of China and around the world China restruck another 46,400,000 of the year 22 dollars and another 128,740,000 year 23 dollars.
In 1949 China contracted with three United States mints to mint another 30,000,000 "junk dollars" dated year 23.
