A collection is a group of items that are gathered and organized based on shared characteristics or themes. People often collect things like stamps, coins, or artworks to enjoy their beauty, history, or rarity. Collections can be personal, reflecting individual interests, or they can be public, displayed in museums or galleries for others to appreciate. Collectors may focus on specific categories, such as vintage toys or rare books, and often seek to acquire new pieces to enhance their collection. The process of collecting can involve research, trading, and attending events like flea markets or auctions to find unique items.
