This auction is consists of the following : Commemorative case with the 30 x medallions, Certificate of authenticity and limited edition mintage, book explaining each collection and original letter from the Africana Commemorative Mint. Additionally I have endeavored to collect as many of the original, or as close as I could find, coins on which this commemorative set is based, less 3 which were either to expensive/difficult to find. These are included. I can give a list of what those are if required. Value of those alone is 70k plus!
