The 1919 Denver Mint issue of the Lincoln cent is a significant collectible coin in numismatics, particularly within the series of one-cent pieces produced by the United States. This specific coin is sought after by collectors due to its historical context and the relatively low mintage compared to other years in the series. Coins from the Denver Mint often have distinctive characteristics such as specific mint marks that indicate their place of origin, which further enhances their collectibility. Collectors frequently seek out uncirculated rolls of these cents, as they hold a higher value and appeal for both investment and hobby purposes.
