I would buy a top of the line gunsafe and bolt it to the floor. I would also purchase additional insurance. Regular homeowners insurance has very low coverage limits for gold and wouldn't even cover 1/10th of the value of an ounce of gold. You can buy various riders to cover the gold, though. 1)Scheduled Personal Property Endorsement (Rider) 2)Stand-Alone Collectibles or Valuable Items Policy (Floater) If you have a substantial gun collection, you should also look into additional insurance. The typical policy has a sublimit for firearms, which is typically 2,500 dollars.
