Collectible coins from the United States, particularly those from the San Francisco Mint, are highly sought after by numismatists. The 1878 dollar coin, often referred to as the Morgan silver dollar, is a notable example, featuring the iconic designs of George T. Morgan. A roll typically contains 20 coins, and the value of these coins can vary greatly based on their condition, rarity, and demand among collectors, with factors such as mint marks playing a crucial role in valuation.
