A coin collector is someone who gathers and studies coins as a hobby or investment. This activity can involve collecting coins from different countries, historical periods, or specific themes. Many collectors enjoy learning about the history and significance of each coin, which can add to the enjoyment of their collection. Coin collecting can also be known as numismatics, which is the study of currency, including coins, tokens, and paper money. Collectors often seek rare or valuable coins, and they may join clubs or attend shows to connect with others who share their interest in numismatics and coin trading.
