Collectible coins, particularly half dollars from the United States, are sought after by numismatists for their historical significance, design, and rarity. The 1940 half dollar, specifically, is part of the Walking Liberty series, which is renowned for its artistic design and represents a pivotal era in American coinage. A 50-cent roll typically contains 20 coins, totaling $10, and is often a convenient way for collectors and investors to acquire these pieces in bulk. The condition, mint mark, and specific historical context significantly influence the value of these coins.
