Collectible coins, particularly those from the United States, can include various denominations and releases, such as the 1 cent (cents) coins. The 1982 penny, minted in Denver, is noteworthy due to the significant change in its composition that year, with some coins made from zinc and others from copper. Collectors often seek out specific years and mint marks, making the 1982 Denver cent a relevant piece for numismatists, especially in relation to factors like preservation quality and rarity. Rolls of these coins can be sought after for both their numismatic value and historical significance.
