My wife and I have bought remodeled and repaired at least nine different homes in our 45 years of marriage.
I have found many things, but the most memorable was what I found in one of the basements.
I was cleaning out a lot of "pack rat" items that were useless to me but was saving useable items like bolts, nuts and tools.
I found several jars of washers, small bolts, and nuts. All the jars had lids and a paper or cardboard lining--for some reason
I would open the jars but one 1/2 gallon jug had a very tight lid. I set it aside and some time later managed to open the jug to see what it contained.
It was completely full of Gold and Silver coins
Just the face value of the coins were well over $1,000
Funny thing is----I finally contacted the wealthy older gentelman that I had purchased the home from, and to my delightment when he laughed and said--"oh everything I left goes with the house"
That was many years ago and I still have the coins in my home safe.
