RE: Time to get physical Hi Bob. Apocalypse, no. As a teen, I did some mining in Australia where all gold had to be sold to the Government, & there was a substantial premium if one sold it on the black-market. That was not a grim time, just a bit different, & no body kissed their aspect good by, but you could make some extra if you broke the law, kinda like bootlegging.
I think there is a chance of a financial melt down, but believe we are headed for something short of that, but still quite bad for some. So (to me) it follows that if you intend to hold a bag of quite valuable coins in your basement, best not let there be a paper trail for crooks or Politicians to follow.
Just my 2 ¢ worth, Regards, Nelson.
