Collectible coins include a variety of types, with trial coins and patterns being particularly notable among them. The 1863 pattern dimes, minted in Philadelphia, are examples of trial coins created to test new designs or minting processes before mass production. These coins are often unique or produced in limited quantities, making them highly sought after by collectors and investors. The 10-cent denomination, commonly known as the dime, features diverse designs and historical significance, adding to its appeal in the numismatic community.
