This was to promote the medal and the method of production. 5) The set is housed in a plaque that is of high quality workmanship and made with archival materials. The plaque is sealed from the environment. 6) I know that this set is rare and I have only found a single reference that is similar to this set ( http://preview.tinyurl.com/bf8b9ol ). The set in the link are completed medals in different finishes and coloration and it by does not cover the 7 depicted stages of production as in the picture. 7) There exists a sister set of exact dimensions and quality for the 1959 Official Hawaii Statehood Medal ( http://preview.tinyurl.com/axje4um ) 8) The May 1960 issue of The Numismatist has an ad from The Coin Currency Institute of NY and CA which is promoting the Hawaii and Alaska Statehood medals simultanously. It may be fesible that both sets were used to promote the respective medals at the same location. Any information provided would be greatly appreciated.
