Help With An Asian Coin?

What you have here is a Chinese cash coin from the reign of the Qian Long emperor (spelled "Ch'ien Lung" in the older catalogues), who reigned from 1735 to 1796. Because he had a very long reign during a time of relative peace and prosperity in China, what you have here is an example of one of the most abundant coins ever produced on this planet. Mintages of these coins exceeded one billion per year at some mints, and there were over 20 mints in operation during this period. This coin was cast at the Board of Revenue mint in Beijing, the most common mintmark of the type. Needless to say, even though they are over 200 years old, they are still extremely common, only worth a dollar or so.

Subtle differences in the style and calligraphy of the characters can extract slightly more information about the coin. In this case, the design indicates an approximate date of 1754-1760.

Oh, and to see the coin "right way up", rotate both pics 90 degrees clockwise.

I found this a long time ago on this site.
I do not remember who posted it there....
A Chinese Coin with the Powers of a Charm
This is an example of an official Qing (Ch'ing) Dynasty minted coin, meant for general circulation, but which was immediately considered to have the powers of a charm. In the year 1713 AD, to celebrate the 60th birthday of Emperor Sheng Zu (Kang Xi), this special issue kang xi tong bao (#24247;#29081;#36890;#23453;) coin was cast with a bronze of a golden color. A 60th birthday is considered a major event in China. In honor of this milestone, the Chinese character xi (#29081;), which is located below the square hole, was written slightly differently. The character would normally have a vertical line at its left. Also, the part of the character normally written as (#33251;) has the center written as a (#21475;) instead. Finally, the upper left part of the tong (#36890;) character, located to the right of the square hole, has only one dot instead of the usual two.
There are several stories connected with this coin that have been passed down for the last 300 years which have given this coin the power of a charm. The stories have turned out to be historically false but continue to be believed. The different versions of the story basically state that the bronze used in the casting of this coin came from the melting down of gold statues of the eighteen disciples of the Buddha. These disciples were called lohan (luohan #32599;#27721;) in Chinese. Because the metal used to cast the coins was believed to be directly associated with these disciples of Buddha, the coin is believed to have special powers and is usually referred to as the lohan coin or arhat money.
Because of its special charm qualities, these coins were given to children in olden times as lunar New Year money (yasuiqian #21387;#23681;#38065;).
These coins were also considered to represent good luck because they commemorated a reign lasting for sixty years which is a complete cycle of the traditional Chinese calendar and thus symbolic of a long life.
Traditionally, these coins also acted as a keepsake or pledge of love between a man and a woman. Some women would even wear one of these coins tied to their hand in lieu of a "gold" engagement ring.
Up until about the 1940's, there was a tradition in the rural villages of Shanxi Province where stylish young men liked to carry a lohan coin between their teeth. This was an attempt to mimic the tradition of stylish young men in the cities who liked to show off a gold tooth.

The last picture is upsidedown, but that coin is 1 tael from French IndoChina, dated between 1943 and 1944.
