Do as you will, but I would NEVER EVER put cash or precious metals in a safe deposit box. Those are worthless except for documents. The gubmint controls the banks, so if the gubmint declares a "bank holiday" and closes the banks, you can't get to your PM's. Furthermore, the gubmint is quite capable of ordering the banks to seize any cash or PM's in safe deposit boxes, or at the minimum, open all of them and force the owners to explain to the IRS the source of said assets, and even tho you obtained them legitimately, do you want to be harassed by the IRS? There are any number of unpleasant scenarios that might ensue.
In short, anything you put in a safe deposit box is at the mercy of the Kenyan Marxist in the WH. You might be comfortable with that. I am not.
Well if I were you, I would not state that on the internet.
If the marxists, and IRS want our silver they only have to get the records from the companies selling precious metals, and they can still come after it no matter what you do, but you just told them yours won’t be in your safe deposit box.
Truth is nothing is safe anywhere at the present time. That is the new normal.
Large white PVC pipe - about 10 inches across (whatever the big size is) with caps at each end, buried in the ground. Can’t burn, water can’t get in it.
Just remember where you buried it and make sure another trusted person knows, or write it in your will. Have some kind of mark that someone can recognize when they read description (or yourself - don’t forget where it is).
Safety deposit boxes are utterly worthless. Suppose the bank fails/gets taken over/there’s a bank holiday etc.
