Collectible coins, particularly those from the United States, often include specific denominations such as half dollars. The 1970 San Francisco half dollar is notable due to its limited mintage, as it was primarily struck for collectors rather than general circulation. Coins from this era often feature the Kennedy design, which became popular after President John F. Kennedy's assassination. The 50-cent roll typically contains 50 coins, making it a common way for collectors to acquire multiple pieces of specific years or mint marks at once.
