Marriage coin charms (traditional Chinese: 夫婦和合花錢; simplified Chinese: 夫妇和合花钱; pinyin: fū fù hé hé huā qián) are a category of Chinese, Japanese, Korean, and Vietnamese numismatic charms that depict marriage, harmonious, and/or sexual imagery. These coin charms often imitate the design of Chinese cash coins, but can exist in many different shapes and sizes.
