Commemorative stamps are special postage stamps issued to honor significant events, people, or anniversaries. Unlike regular stamps, they are often produced in limited quantities and are designed with unique artwork that reflects the theme they celebrate. These stamps serve both a practical purpose for mailing and a collectible appeal for enthusiasts. Typically released on specific dates, commemorative stamps can mark occasions such as national holidays, historical milestones, or the achievements of notable individuals like scientists or artists. Collectors often seek these stamps for their artistic value and historical significance, making them a popular item in philately, the study of stamps.
