See my post #8 on this thread.
I just bought 48 more old US silver (90%) dollars friday for $12.50 each.
I agree silver is the way to go.
If goods become scarce, people buying with silver and gold will go to the front of the line.
But “scarce goods” means you will be buying small amounts at a time, so gold almost makes no sense, the seller can’t/won’t make change and you end up paying a huge premium.
