Collectible coins, often referred to as numismatic coins, encompass a wide variety of types including historical, commemorative, and bullion coins. One notable example is the Massachusetts silver coins minted in 1652, which are among the earliest coins issued in what would become the United States. These coins include the Pine Tree Shilling and other denominations, featuring distinctive designs that reflect the early colonial period. Their rarity and historical significance contribute to their value in the numismatic market.
