Collectible coins, often referred to as numismatic coins, include a variety of types based on their historical significance, rarity, and condition. The Coronet Head Cent, minted in the United States from 1816 to 1839, is an example of a classic coin design featuring a portrait of Liberty. The specific 5 Dollar gold coins, known as half eagles, were minted in various years including 1816 in Philadelphia, and are sought after for their gold content and historical value. Collectors often focus on aspects such as mint marks, grading, and provenance when evaluating these coins.
