The manufacturer has the following description of this coin:
"Launched on November 14 1969, Apollo 12 landed on the moon in the Ocean of Storms. The Lunar coordinates of the landing site were 3.01239° S latitude, 23.42157° W longitude. The craft needed a precise landing to find a nearby probe which had previously landed. Success within 200 feet of a previous probe, allowed the astronauts to collect the probe. Kinda like finding a geocache on the moon! Antique Gold (AG) finish."
This coin is trackable on www.geocaching.com with its own icon.
Here are some futher facts about the Apollo 12 mission, which may not be completely forgotten, but is heavily overshaded by the previous, far more famous Apollo 11 landing, which is usually considered an event of World history significance, and the subsequent Apollo 13 mission, which was a failure, but in which the astronauts were only just saved:
The second manned lunar landing mission, Apollo 12 launched from launch pad 39-A at Kennedy Space Center in Florida on November 14, 1969 via a Saturn V launch vehicle. The Saturn V was developed by the Marshall Space Flight Center (MSFC) under the direction of Dr. Wernher von Braun. Aboard Apollo 12 was a crew of three astronauts: Alan L. Bean, pilot of Lunar Module (LM) Intrepid; Richard Gordon, pilot of the Command Module (CM) Yankee Clipper; and spacecraft commander Charles Conrad. The LM, Intrepid, landed astronauts Conrad and Bean on the lunar surface in what’s known as the Ocean of Storms while astronaut Richard Gordon piloted the CM, Yankee Clipper, in a parking orbit around the Moon. Lunar soil activities included the deployment of the Apollo Lunar Surface Experiments Package (ALSEP), finding the unmanned Surveyor 3 that landed on the Moon on April 19, 1967, and collecting 75 pounds (34 kilograms) of rock samples. Apollo 12 safely returned to Earth on November 24, 1969.
If you are wondering, what an oldfashioned sailing ship is doing on the coin, this is because the official mission logo looked like this:
The name of the Command Module was "Yankee Clipper" - thus the symbology with the clipper ship.
The other side of the coin shows a space helmet, and reflected in the visor is an astronaut, freely floting in space with a socalled Manned Maneuvering Unit (MMU). The choice of this picture is actually rather stange, since it has nothing, whatsoever, to do with the Apollo 12 mission. MMU was used in three Space Shuttle flights in 1984, and neither before nor since, and have been nowhere near the Moon.
Also the note stating that the astronauts "collected the probe" is not entirely accurate. The Surveyer 3 probe, which had landed more than 2 years previously, weighed 302 kg, and it was impossible to freight the entire probe back to Earth. Therefore, about 10 kg of parts were removed from the probe, including a fairly large TV camera, and brought back to Earch. The camera is on display today at the National Air and Space Museum in Washington. D.C.
