Marriage coin charms 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.

Japanese numismatic charms, also known as Japanese amulets, Japanese talismans, or simply Japanese charms, refer to a family of cash coin-like and other numismatic inspired types of charms that like the Korean and Vietnamese variants are derived from Chinese numismatic charms, but have evolved around the customs of the Japanese culture. Although most of these charms resemble Japanese cash coins and the amulet coins of China, they contain their own categories unique to Japan. In the case of these coins, "charm" in this context is a catchall term for coin-shaped items which were not official money. However, these numismatic objects were not all necessarily considered "magical" or "lucky", as some of these Chinese numismatic charms can be used as "mnemonic coins".
