The 1998-S U.S. Mint Clad Proof Set in Original Government Packaging (OGP) is an official U.S. Mint collector issue that represents the final year of traditional Proof coinage before the introduction of the popular 50 State Quarters Program. Struck at the San Francisco Mint, this five-coin set includes the Lincoln Memorial Cent, Jefferson Nickel, Roosevelt Dime, Washington Quarter, and Kennedy Half Dollar, each bearing the distinctive "S" mintmark. Every coin was struck multiple times using specially prepared planchets and highly polished dies, producing brilliant mirror-like fields, frosted design elements, and exceptional detail. Many examples display beautiful cameo or deep cameo contrast, making them highly desirable to collectors. Preserved in the original U.S. Mint lens and accompanied by the official government packaging, this set remains exactly as issued by the Mint, ensuring authenticity and lasting collector appeal. With an official mintage of 2,086,507, the 1998-S Clad Proof Set combines one of the decade's lower mintages with the historical significance of marking the end of an era in modern U.S. coinage. Combining premium Proof quality, original government packaging, and enduring numismatic importance, the 1998-S Clad Proof Set is an outstanding addition to any United States coin collection.
