1. No, you cannot take physical possession of your metals at home.
Gold and other bullion are “collectibles” under the IRA statutes, and the law discourages the holding of collectibles in IRAs. There is an exception for certain highly refined bullion provided it is in the physical possession of a bank or an IRS-approved nonbank trustee. This rule also applies to an indirect acquisition, such as having an IRA-owned Limited Liability Company (LLC) buy the bullion. IRA investments in other unconventional assets, such as closely held companies and real estate, run the risk of disqualifying the IRA because of the prohibited transaction rules against self-dealing.
