The Wikipedia article of the day for July 20, 2021 is Apollo 11 50th Anniversary commemorative coins.
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.
