The history of silver pill boxes is linked to the Victorian era, when manufactured pills became popular and ornate pill boxes became a must-have accessory. Pill boxes were made from a variety of materials, including silver, gold, stone, wood, and bone. They were often portable and could be kept in a purse, on a bedside table, or on a dressing room vanity.
