Collectors are individuals who gather and organize items of interest, often focusing on specific categories such as stamps, coins, or art. They may seek rare or unique pieces to enhance their collections, which can serve as a hobby, investment, or a way to preserve history. Many collectors participate in communities or clubs where they can share knowledge, trade items, and attend events like flea markets or auctions. Collecting can also involve research to understand the value and significance of items, making it a rewarding pursuit for those passionate about their chosen field.
