Collectible coins, such as the 2018 Silver Eagle minted in San Francisco, are sought after by numismatists and investors alike. The American Silver Eagle is a one-ounce silver coin that features a design of Lady Liberty and is known for its high silver content and distinctive mint mark, which indicates its origin. Coins from the San Francisco Mint often carry a premium due to their limited production and collector demand. These coins are not only valued for their metal content but also for their numismatic significance and potential appreciation in value over time.
