Seems to me platinum bulion coins only sold overseas not like the proof versions here also from 1988,as I haven't seen any for resale here despite in 1988 only the 1oz and the 1/2oz platinum bullion versions conbined total sale were well over 100,000 . 110,711 to be exactly. 128,288 in 1989. They also sold other version especially from 1992 when everything from the 1kg to the 1/20 oz were available. Sales started to decline under 6000 in 1997 and under 3000 in 2000 for this two version together when finally production of all these bullion version coins stopped in 2000.
