I made the first move by moving my Roth IRA money into a cash account within Vanguard. This way there is no tax penalty and when I pull the trigger Regal Assets can roll it over. I may go with 75% silver and 25% gold.
Since it's an IRA the physical metal has to be stored by them (actually a company they use). They charge $225 a year to store my coins and wave the first year's fee. When I'm 59-1/2 I can get the physical metal or have cash sent to me. Or if the SHTF before turning 59-1/2 I can request the coins and deal with whatever penalties the gov't tries to nail me with. I'll pay them with their Monopoly money and keep the silver and gold.
