I think that is a bank thing. Not a legal issue.

But I'm not sure of that. I think some little podunk bank does not want thieves to think a bunch of rich dudes are stashing billions of bullion in safe deposit boxes. Kind of would put a lot of strain on security, which in a lot of small banks is minimal. So in their safe deposit agreements they state and you agree not to keep cash and PM's. If you do it, you do it at your own risk and against the agreement. So you have no foot to stand on if you get robbed in your box.

That is my thought. Not sure if it is correct. I don't think there is anything illegal about it. But who knows after 911 and the Patriot act. Might be illegal to take a piss in your pasture, because it is a national security risk. I know they have tightened up cash transactions.
