got me curious so i looked it up and they were called dragées apparently

since 1906, U.S. regulations have prohibited the manufacture or sale of any food that uses any metal or mineral substance—including silver—as a food coloring, coating, or additive.[8] The U.S. Food and Drug Administration considers the silver and gold metallic-finish sugar dragées to be inedible, and they may be sold only when accompanied with a notice that they are to be used for decorative purposes only.[8] Almonds that have been coated the same way are not permitted at all.[8] Although metallic-finish dragées can be purchased in 49 U.S. states, they are no longer sold in California.[9]
