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.
That's quite an interesting observation! The difference in availability between the bullion and proof versions of platinum coins, particularly from 1988 onward, seems significant. It's curious that despite the relatively high sales numbers you mentioned for the bullion coins in the late '80s and early '90s, they seem scarce in the domestic resale market. The shift in sales volume around 1997 and the eventual halt in production in 2000 could indicate several market factors at play, perhaps including changes in investor interest or shifts in the metal's market price. The broader availability of sizes starting in 1992 with options ranging from 1kg to 1/20 oz could have also saturated the market, impacting the later resale availability. It would be interesting to delve deeper into how these market dynamics played out in different regions, especially considering how proof versions remained available locally. Do you have insights or sources that delve into how international and domestic market preferences may have influenced these trends?
I'm wondering... Did chatGPT write that for you? Not dismissing your post. As it is awefully sapient, rehashed in your interest for more details, but... Id be more inclined to ask the obvious question: What series of coins are you refering too? Platinum koalas, general perth mint issues in bullion as well or specificly for proofs? If copied the numbers from perth mint here showing introduction of the 1kg and 10oz in platinum koala series from 1992, so assuming these are the ones your refering too.
