Only 3 people own world wide? Anyone seen these before?

Help, thank you, now for the short story.

1000 of these were minted, all sent to PNG, to be released at the 100th year Royal Anniversary.

Covid totally smashed the place. Coins got lost and re appeared again 2023.

As far as I'm aware, one person purchased 900 of them, another purchased the other 100. I took 5 of these coins as part trade on a watch about a year ago. So now, I own 5.

I can find nothing online. Nothing about any being sold. I've sent msgs to the Perth Mint asking what the go is.. had some small talk and then they just never got back to me, they couldn't confirm where they went or how they were sold ( I have these messages )

So.. any experienced coin dabblers keen to try and help me out, it would be greatly appreciated.

How is something priced when none have been sold? I can't find anything really about them online, especially about any sales.

Any help would be appropriate 🙏
