Just leave all of them on a porch with a light over them. No one would try stealing something so obviously in the open. Just kidding of course. Nothing beats a safe deposit box at a bank. Although those are getting a bit expensive. I just got a letter from one of my banks saying how my safe deposit box will now be costing me more.
I use both bank deposit boxes and a big anchored safe. Here is a good app to have and use, I get the daily emailed incident reports to me, keep on the look out for crime waves in your neighborhood such as break-ins, robberies, etc.
