This listing is for The Presidential Medals Cover Collection 1-40 24k Gold Electroplated Set. The Presidential Medals Cover Collection is a set of historical mementos issued by the private company, the Postal Commemorative Society, primarily in the 1980s. Each item in the collection features an official medal produced by the U.S. Mint, which the society then electroplated in 24-karat gold. Each medal is housed in a philatelic envelope, known as a first-day cover, which bears one or more U.S. stamps relevant to that president, officially postmarked on the stamp's first day of issue. Great Find!!!
