Silver coins are currency made primarily from silver, a precious metal known for its value and durability. Historically, they have been used for trade and commerce, often featuring designs that represent the issuing authority, such as kings, queens, or national symbols. Silver coins can vary in purity, with many containing 90% silver or more. Today, silver coins are popular among collectors and investors. They are often minted in specific weights, such as one ounce, and can be found in various forms, including bullion coins and commemorative coins. The value of silver coins is influenced by the current market price of silver and their historical significance.
