Collectible coins refer to coins that are sought after by collectors for their historical significance, rarity, or unique characteristics. In the United States, one prominent type is the Gold Eagle, which was first minted in 1986 and contains one troy ounce of gold. The 20 Dollar Gold Eagle coins, including the 1998 issue, were produced in various mints, with Philadelphia being one of the key minting facilities. These coins are highly valued by numismatists and investors due to their gold content and collectible appeal.
