The official United States Mint Presidential $1 Coin Proof Set™ contains the four new Presidential $1 Coins.
Proof coins are extraordinarily brilliant with sharp relief and a mirror-like background. Their frosted, sculpted foregrounds give them a special “cameo” effect, created by the exacting proofing process. Proof blanks are specially cleaned, polished and treated to ensure high-quality strikes. The blanks are then fed into presses fitted with hand-polished dies and struck at least twice to ensure sharp, high relief. The coins are then packaged in presentation cases to showcase and preserve their exceptional finish.
This set comes in a special sealed airtight plastic holder.
