A coin collector is someone who collects coins, tokens, and other forms of currency. They may collect coins from different countries, eras, or mints. Common items a coin collector might use include a SOFA to sit on while sorting coins, a METER to measure the size of coins, a numismatist to help identify coins, a SLOT to store coins, a JAR to hold coins, a piggybank to save coins, and a parkingmeter to pay for parking.
