If your grandparents are old enough to have lived through the great depression, and you have to one day go through their things after the pass to get rid of things, please remember to check the following places for hidden money: -open all books, flip through all pages, ESPECIALLY ENCYCLOPEDIAS. -the water tanks of toilets -open the face plates to all electrical sockets and verify that the socket is real and not just a decoy that is really a little box full of cash -open all records sleeves, pull out the records and check for hidden cash -those canned/jarred food, look under all of them, if any feel too light to be preserved food, open that can or jar -If they have drop ceiling, get your head up there with a flashlight and check the tops of all panels -look for any mismatches on walls or pourced cement, they may have buried something the in house structure -odd spots in the yard, might be worth renting a metal detector and giving the yard a once over -open all air vent covers and have a good look inside, around corners. Scoping cameras have some affordable options -pull out all dresser drawers and look for anything taped inside the dresser, or secret sliding compartments on the drawers themselves -cash sealed in zip-lock bags at the bottom of bins containing flour, coffee, sugar etc. -it could be worth it to get one of those new stud finders that show an image for what is behind a wall, it is not uncommon for people of that age to bury something in a wall and have a full finish on the wall, their thinking was if they needed to access this money by breaking the way, they were probably going to abandon the house anyway, so wanted to make it extremely difficult to find by accident.
