The International Olympic Committee Centennial (1896-1996) 5 year programme was prepared by 5 different countries; Canada-1992, Australia-1993, France-1994, Austria-1995 and Greece-1996. The Royal Australian Mint produced an Olympic 1993 $20 silver swimming relay team (friendship) proof for Akai electronics in a specially prepared official timber case. The edge is inscribed 'Citius Altius Fortius'. This is the only one we have ever seen or offered!
