Collectible coins are unique pieces of currency that hold value beyond their face value due to rarity, historical significance, artistic design, or demand among collectors. In the context of the United States, types such as the G-1 grade indicate coins graded by their condition, with G-1 being a low grade representing significant wear. Patterns are experimental or prototype coins minted to test designs or compositions before official production. The year 1915 features notable collectible coins, including the 1915-S Panama-Pacific Exposition commemorative coins, which were produced to celebrate the San Francisco fair and are highly sought after by collectors.
