The Apollo 11 50th Anniversary commemorative coins were issued by the United States Mint in 2019 to mark the 50th anniversary of the first crewed landing on the Moon on July 20, 1969, by Apollo 11 astronauts Neil Armstrong and Buzz Aldrin. There is a gold half eagle (five-dollar coin), two sizes of silver dollars, and a copper-nickel clad half dollar, all with the same design and curved, with the obverse concave and the reverse convex. The obverse shows a bootprint on the lunar surface, and the reverse (pictured), based on a well-known photo by Armstrong, depicts the visor of Aldrin's space suit, reflecting Armstrong, the U.S. flag and the Lunar Module Eagle. The depiction of Aldrin made him the seventh individual depicted on a U.S. coin to be alive at the time it was struck. The program was the most successful U.S. commemorative coin issue since the 2014 National Baseball Hall of Fame coins, with more than 600,000 Apollo 11 coins sold. The larger silver dollar won the Coin of the Year Award for 2019-dated issues.

They were mothers and fathers; husbands and wives; sisters and brothers; sons and daughters; friends and neighbors. They had hopes for the future and dreams that were not yet fulfilled. And if there's anything to take away from this tragedy, it's a reminder that life is fragile. Our time here is limited and it is precious. And what matters in the end are not the small and trivial things which often consume our lives. It's how we choose to treat one another, and love one another. It's what we do on a daily basis to give our lives meaning and to give our lives purpose. That's what matters. That's why we're here.   --Barack Obama <https://en.wikiquote.org/wiki/Barack_Obama>
