Collectible coins are often sought after by numismatists and investors for their historical significance, aesthetic appeal, and potential appreciation in value. The United States Gold Eagle coins, particularly the $5 denomination, are part of a series that features the iconic designs of Augustus Saint-Gaudens and Miley Busiek. The 1998 issue was minted in Philadelphia and is notable for its limited production and gold content, making it a popular choice among collectors seeking both beauty and investment potential.
