Vault Protector coins (traditional Chinese: 鎮庫錢; simplified Chinese: 镇库钱; pinyin: zhèn kù qián) 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.
