What is your "I could have been rich" story?

My great uncle was a nice dude fucked up from war. It made he introverted and he turned to trucking and the road to make ends meet. It was basically all he ended up doing. He never married or had kids, and stacked up all this cash. Before he died, he had put 1 million in cash in a suitcase, put it in the trunk of a car, and gave it to my grandparents. They couldn't get the trunk open, didn't investigate, sold the car.
