Some have been saying the Aussie dollar might hit 70 during 2024, obviously if the rally in precious metals continue, even if the AUD does rise against the USD those Aussies that have metal especially silver may do ok.
For new folk buying silver, be aware, that if you buy low premium bars, you'll be tied to the spot price of silver, but if you buy bullion coins, which have a higher dealer mark-up you have the potential to buy a coin / coins that have a higher "numismatic" value in the weeks, months or years following your purchase; having said that, some of the bullion coins don't do so well but in a bull-run (prices rallying higher) you'll do pretty good if the rally is substantial.
Always remember to factor in the total price of the silver you buy, including postage, storage and selling on auction sites.
My tip would be to consider bullion coins that have a limited mintage or if you were lucky enough to buy unlimited mintage bullion coins in bulk when silver was much cheaper, example March 2020.
Lastly, plan your silver investment because one day the AUD may be well above the USD as it was in 2011, reaching $1.10+ July 2011.
A low Aussie dollar means it's more expensive to buy precious metal and if you sell precious metal when the AUD USD exchange rate is higher you'll get less for you metal. The objective is to buy metal when the AUD is on par or higher than the USD and sell it when the AUD is lower.
Hence, sometimes it's good to have bullion coins with a low mintage that gain numismatic value; you can off-set a rising USD against the AUD but not so much with generic silver bars.
