Collectible coins from the United States include various types, such as Mint Sets, which are collections of coins produced by the U.S. Mint and packaged together for collectors. The 1978 Mint Set, specifically from the Philadelphia Mint, features coins circulating during that year, including the iconic Lincoln penny (1 cent). These sets are often sought after for their unique packaging, quality, and historical significance, making them a popular item among numismatists.
