Collectible coins encompass a variety of types, including those issued by the United States of America, such as the 10 Cents Dime. Among the notable collectible issues are patterns and trial coins, which were created to test new designs or modifications before mass production. One of the most famous examples is the 1804 silver dollar, which is often referred to as the "King of American Coins." Many of these coins were struck at the Philadelphia Mint, the first mint in the United States. Collectors highly value these rarities for their historical significance and numismatic appeal.
