BANGOR, Maine (AP) A Maine artist’s Apollo 11 design will be on commemorative U.S. coins.

The Bangor Daily News reports Belfast artist Gary Cooper won a U.S. Mint competition marking the 50th anniversary of the Apollo 11 mission.

Cooper said he remembered watching the lunar landing and watching astronaut Neil Armstrong take his first step on the moon.

Cooper’s design features Armstrong’s footprint in the lunar dust.

Cooper said he’s a lifelong coin collector. As a teenager, he offered to help design the Eisenhower dollar coin.

Since then, he’s submitted designs to the U.S. Mint. His Apollo 11 design was the first to make the cut.

His design will be on four coins: a $5 gold coin, a silver dollar coin, a half dollar clad coin and a $1 silver proof coin.
