Chinese Coins - rare china gold coins
Chinese money coins originated from the barter of farming tools and agricultural surpluses. Around 1200 BC, smaller token spades, hoes, and knives started to be used to conduct smaller exchanges with the tokens later softened down to supply real farm implements. These tokens came to be used as media of exchange themselves and were known as spade money and knife money.The earlier coins were cast to weight standards in a direct relationship with the denominations, so if you weighted a coin at 12 grams it was almost certain a 1 Liang (or 1 Jin) denomination. During the Chin Dynasty, around about 250 BC, this changed and be start to see coins issued with denomination marks that bare no connection to the weight of the coin. This is best seen on the Ban liang ( 1/2 Liang ) coins of the State of Chin which can change in weight significantly but the earliest massive diameter issues weigh at least six grams (and often significantly more), but the size and weight gradually declined and when they were last issued in the Han Dynasty are commonly seen at three grams or even less, but still with the Ban Liang denomination on them.
The Koreans, Japanese, and Vietnamese all cast their own copper cash in the second part of the second millennium like those employed by China.
The last money coins were struck, not cast, in the reign of the Qing Xuantong Emperor just before the fall of the Empire in 1911. The coin continued to be used unofficially in China until the mid 20 th century.
