Vault protector coin
Vault Protector coins were a type of Chinese numismatic charm coins created by Chinese mints. These coins were significantly larger, heavier and thicker than regular cash coins and were well-made as they were designed to occupy a special place within the treasury of the mint. The treasury had a spirit hall for offerings to the gods of the Chinese pantheon, and Vault Protector coins would be hung with red silk and tassels for the Chinese God of Wealth. These coins were believed to have charm-like magical powers that would protect the vault while bringing wealth and fortune to the treasury.
Vault protector coins were produced for over a thousand years in China, with roots in the Southern Tang dynasty and production continued into the Qing dynasty.
History
Early history
There is some speculation by the Chinese numismatist Guan Hanheng that an enormous silver Ban Liang cash coin manufactured by the Kingdom of Qin in the year 336 BC had been cast to serve as some form of vault protector. In his book Ban Liang Huobi Tushou, Guan argues that large silver Ban Liang was "cast in 336 BC to commemorate the firing of the furnaces that began production of the first Ban Liang cash coins of the Qin state" and that the large silver Ban Liang cash coin did not see any circulation as it was a commemorative issue.Southern Tang

Only one of these vault protector coins is known to exist and it was owned by a coin-collector from the city of Tianjin named Fang Yaoyu during the beginning of the twentieth century and it was later owned by another private coin-collector called Chen Rentao before it ended up in the collection of the National Museum of China during the 1950s.Qing dynasty
Shunzhi era
Following the expansion of Qing rule into the Central Plain in 1644, the empire established new mints in Beijing. Almost immediately did the Qing start imitating Ming dynasty coinage, including vault protector coins. Two central government mints were opened in Beijing and they began to cast the Shunzhi Tongbao cash coins closely modeled after the cash coins of the preceding Ming dynasty. A special Shunzhi Tongbao vault protector coin was cast that was 6 centimeters in diameter and contained the Manchu reverse inscription "Boo Yuwan". Another variant of this vault protector coin exists which has the Chinese character "工" on the right side next to its square centre hole on its reverse side.Xianfeng era
The Leizhou City Museum in the city of Leizhou, Guangdong and the Palace Museum in Beijing both own a Qing dynasty era Xianfeng Tongbao vault protector coin. The reverse inscription of this vault protector coin reads Da-Qing Zhenku. These coins have a diameter of 14 centimeters. The square centre hole is 2.5 centimeters in diameter, the vault protector coin weighs 1.05 kilograms. Only 5 of these vault protector coins were ever produced and during the beginning of the Republic of China, a eunuch had stolen all of them, the aforementioned two cash coins remained in China while the eunuch sold the other 3 Xianfeng Tongbao vault protector coins for what was purported to be "a large amount of money" to a British man. A description of this vault protector coin also appears in the book "Zhongguo Guqian Daji" written by Hua Guangpu, where it is valued as being worth 1.200.000 yuan. The Leizhou City Museum came in possession of this coin during the 1950s, prior to this it was privately owned.During the Xianfeng era another type of vault protector coins was cast by the Ministry of Public Works with the obverse inscription Baoyuan Juzao. The reverse inscription of this coin reads Zhenku. This vault protector coin is very large in its size and has a diameter of 11.52 centimeters, its square centre hole is 1.8 centimeters in diameter, and it has a weight of 837.3 grams.

Qixiang / Tongzhi era

The reverse sides of these vault protector coins contained the characters Shengbao. In his book "Coins of the Taiping Heavenly Kingdom", Chinese numismatist Ma Dingxiang notes that the vault protector coins of the Taiping Heavenly Kingdom were manufactured for the mints of Hangzhou, Hunan, and Suzhou. There are only five or six Taiping Heavenly Kingdom-made vault protector coins known to exist and these coins all tend to display some very slight differences between them.A specimen that was previously in the collection of Ma Dingxiang and sold at auction held in the year 2011 for an amount of $111,286.
Modern reproductions
