Store the bullion inside an old computer case. A burglar is not very likely to steal a worthless, old computer nor is he very likely to look inside the case.
How about the back of an old refrigerator sitting in the corner of your garage. Fill the refrigerator with old tools and junk so it looks like a makeshift storage cabinet. Heck, you can rip off the door and give it a more "open" look. Your wife might complain about the messy look though.
where............................... why hide it at all? just put a sign on your door and or windows exclaiming "THIS HOUSE HAS NO VALUABLES!" they'll just move on!
Don't put them all in one place and make sure someone else knows where they are in the event you can't retrieve them.
:secret: If I told anyone here where to hide their silver, I would be giving away privy information, which is untoward and compromising of my silver's long term security. So there.
In the center of a 40lb block of gold. Nobody would look for it there. All kidding aside. I have seen door stops in homes with some pretty interesting contents. Also, if your a burgler, never ever check the freezer..
Mick , wherever you hide it , if they have any collecter value , make sure its not too humid or hot , but if its just bullion , just remember where you hid it . Rusty
