It's only a guess however with the redirection of resources at the Perth Mint to bar production, I think this year's mintage of the Kookaburra and Lunars coins are going to be lower than normal! It's only another 3 1/2 months before the 2021 coins are supposed to be released.
Depends on the legislation passed regarding minting of the coin and any associated limitations ( I haven’t read series 3 legislation) Anyone that has read might be able to confirm mintages and if any minting allowed in the future In the series two lunars they reminted up to the 300,000 limit the 1 oz silver and 1 kg lunars were able to be minted until the end of the series.
