This coin features the same design as the regular Silver Eagle, but with a reverse proof finish, which means that the design elements are polished to a high degree while the background is frosted. The “S” mint mark indicates that the coin was struck at the San Francisco Mint. The PCGS PR70 grade indicates that the coin is in perfect condition and has no flaws or blemishes, even under magnification. The First Day of Issue designation means that the coin was submitted for grading on the first day of its release, adding to its rarity and collectability.
