All of the coins are struck in proof quality at the San Francisco Mint and has the S mint mark on the obverse. Due to the bright mirror proof finish of the coin reflections can be seen in the picture of the actual pictured coin from the scanner. Mint proof coins feature sharp relief and a mirror-like background. Their frosted, sculpted foregrounds give them a special cameo effect. Proof blanks are specially treated, polished, and cleaned to ensure high quality strikes.
The blanks are then fed into presses fitted with specially polished dies and struck at least twice to ensure sharp relief. The coins are then packaged in a protective lens to showcase and maintain their exceptional finish.
