Coins - 1999 Proof Set Certificate of Authenticity and Coin Specifications

The folded card in the 1999 proof set included a message from the Director of the Mint which certified the nine proof coins, described the proof set process and provided the proof coins' specifications. 

The outside of the 1999 Proof Set Certificate of Authenticity has a shiny surface. The front of the certificate includes the title, "Certificate of Authenticity 1999 United States Mint Proof Set" in a dark blue font. Above the title is the US Mint Seal in dark blue. Inside the outer circle of the seal, the words "TREASURY" and "UNITED STATES MINT" show against the white background. In the inner circle, a white shield includes scales at the top, a chevron with thirteen stars in the middle and a key at the bottom. The back of the card provides the specifications and characteristics of the cent, nickel, dime and half dollar proof coins (see below for table).

The inside of the card uses a matte finish for the background of the Director of the Mint's message and the specifications for the five state quarter proof coins.

The Director's message states:

1999 United States Mint Proof Set™
Certificate of Authenticity

The United States Mint certifies that this Proof Set of current United States coinage was produced and packaged at the United States Mint, San Francisco, California. Each coin bears the "S" mint mark of that facility.

United States proof coins are produced from carefully selected planchets, or coin blanks, that have been burnished to a high luster. The polished blanks, which are carefully handled to minimize scratches and abrasions, are struck on specially adapted coining presses. Each coin is struck at least twice to bring forth the most minute detail with remarkable clarity.

The 50 State Quarters™ Program is authorized by Public Law 105-124. The coins are created to honor each of the 50 States in the order in which they entered the union. Their designs depict the history, geography, and the rich diversity of our national heritage.

Philip N. Diehl
Director
United States Mint
