My wife's dad used to own a liquor store before retiring; he kept crates of liquor and cigars in a side area of the garage. Don't know why my mother-in-law kept it for 3 decades after his passing, she kept everything he owned including his clothes. Besides the other stuff, there was lots of lumber and boxes of jars packed into a storage room under the house, and lots of lumber packed under the front stairs of the house (3 levels). My wife and her sister were discarding clothes and my wife chastised her sister for simply throwing clothes into discard bags. My wife went through every pocket and found money and jewelry items, that otherwise would have been discarded. We stopped hiding money in our own clothes after that!
In her defense, Grandmother-in-law probably had some form of dementia (I didn't know her all that well). That, combined with living through the depression made a squirrel out of her.
