Collectible coins encompass a wide range of numismatic items, including standard currency, rare coins, and special editions. In the United States, the 50 cents denomination, commonly represented as half dollars, has various collectible versions. Patterns and trial coins, such as the 1935 series, were produced to test designs or minting processes but were typically not released for circulation, making them highly sought after by collectors. The lack of information on certain coins within these categories can sometimes add to their intrigue and value among numismatists.
