Collectible coins include a wide variety of types, including gold, silver, copper, and bronze pieces, sought after for their historical significance, rarity, and condition. One notable example is the Saint Gaudens Double Eagle, which features a design by sculptor Augustus Saint-Gaudens. The 1923 Denver issue is particularly prized among collectors due to its limited mintage and representation of the gold standard era in the United States. These coins typically command high values in the numismatic market, especially in well-preserved grades.
