Many of these went above and beyond the “coin silver” standard of .900 fine to the sterling standard of .925 fine. A few mints did something progressive for the times by producing medals made of truly pure .99 fine silver.
The Medallic Art Co. was one of many private companies making big silver medals throughout the final decades of the 20th century. A typical weight for one of these was 4.3 ounces, like the circa 1970 Kennedy and Apollo 11 medal. This medal was marked on the edge as being made of .999 fine (pure) silver.
The design was popular because it told the story of an important decade. On one side was a 1961 quote from the president saying that the United States should put a man on the moon before the end of the decade. The other side showed that very event and its date, July 20, 1969.
