Collectible coins, particularly those from the United States, encompass a variety of types and denominations. Half dollars, such as the 1940 issue minted in San Francisco, are notable among collectors due to their historical significance and relatively low mintage. The 50-cent roll of half dollars typically contains 20 coins, which may include various designs, such as the Walking Liberty or Franklin half dollars, appealing to both numismatists and investors alike. This specific year, 1940, is often sought after by collectors due to its availability and condition.
