1998 United States Mint Set in Original Government Packaging. In many ways, the 1998 Mint Set represented the end of an era. The 1998 Mint Set contained the final Washington Quarters before the obverse design would be modified and the reverse would feature five different annual designs commemorating the states. The other coins included were the Kennedy Half Dollar, Roosevelt Dime, Jefferson Nickel, and Lincoln Cent. The ten coins were packaged in two separate mylar packs with tokens representing the Philadelphia and Denver Mints. The outer envelope depicted the circulating coins against a blue background and specifically displayed the reveres design of the quarter. The envelope carried the title “From the United States Mint… The 1998 Uncirculated Coin Set”. An additional message was included at the bottom of the envelope: “This collector’s set includes two 1998 Washington Quarter Dollars. This is the last time the heraldic eagle reverse will appear until at least 2009.”
