We don't know, and honestly, neither do you. Here's a few things we do know: 1) when FDR required the American public to turn in gold, most experts believe only a small minority actually did turn in their gold; 2) It would be nearly impossible for the government to locate, much less confiscate a commodity that has been freely purchased, sold, and traded for decades and; 3) If the government did confiscate precious metals, we have no idea what they would confiscate, and what—if any—coins or bars they would exempt from confiscation.
