Collectible coins, particularly in the United States, encompass a variety of types including numismatic coins, bullion coins, and commemorative issues. One notable example is the American Liberty Gold coin series, which features iconic designs symbolizing American ideals. The 1893 twenty-dollar gold piece minted in Philadelphia is a significant collectible due to its historical context and limited mintage. These coins are often sought after by collectors for their artistic value, rarity, and the investment potential they offer in the numismatic market.
