I urge caution hiding valuables in anything that can be needed or used. All the above ideas are great. They show the degree of 'sneakyness' all us 'jus litttle ole me's' are capable of employing.
In the coming problems, we do not know if we will be burgarlized for money, food, or captive slave.
Before you employ food cans, clothes, or other items that may be used, think of yourself as a starving, rag tattered person in need of food, clothes and trade items.
If you entered your house, what would be the first things you would take.
Cans of food, IMHO are the worst hiding places possible.
