Collectible coins are categorized based on rarity, historical significance, condition, and demand among numismatists. The United States offers a notable example with the 1 One Cent Penny, which has various editions, including the famous 1909-S V.D.B. penny. Additionally, coins from the Confederate States of America, such as those minted in 1861 in New Orleans, represent a unique segment of American numismatics, reflecting the turbulent history of the Civil War era and the scarcity of Confederate currency. These coins are often sought after by collectors for their historical context and limited production.
