query: What are marriage coin charms and what do they depict?
answer: Marriage coin charms are Chinese, Japanese, Korean, and Vietnamese numismatic charms depicting marriage, harmonious, and/or sexual imagery.  They often imitate Chinese cash coins but come in various shapes and sizes. Depictions include symbols of reproduction (dates, peanuts, lotus seeds), fertility (pomegranates), male offspring (chestnuts), dragon and phoenix (representing union or imperial power), and scenes of sexual intercourse.
