Collectible coins encompass various types, including numismatic coins, commemoratives, and bullion coins. The United States quarter, specifically the 25 cents coin, has a long history and is a popular collectible, with specific issues like the California Fractional Gold coins being sought after by collectors for their unique design and historical significance. The 1864 coinage year is notable for its shifts in design and metallurgy, particularly with the introduction of the bronze cent and the various quarters produced during that time, which can be valuable based on rarity and condition.
