Coins - 1991 Prestige Set Certificate of Authenticity and Coin Specifications

The US Mint printed the Certificate of Authenticity for the 1991 Prestige Set on an off-white paper flecked with silver using black and silver ink.

The paper is slightly smaller than a legal page of 8 1/2 by 14 inches. Information is printed on both sides with the paper folded in a tri-fold before being added to the Prestige Set package.

The front of the folded certificate shows "Certificate of Authenticity" printed in silver above "MOUNT RUSHMORE ANNIVERSARY COINS" printed in black. In the center, an emblem celebrates the golden anniversary of the monument. (see close-up below). Just below the emblem reads "PRESERVE AMERICA'S FINEST FEATURES" and further down in silver print "1991 PRESTIGE SET."

The emblem not only celebrates the 50th anniversary, but it also provides a glimpse of what the commemorative coins show on their obverses.

On the back, the Mint's seal in silver ink is printed above "Department of the Treasury United States Mint" in black ink.
