When I was a kid, my aunt worked at Whites 5&10. A little department store in Illinois. Every birthday and Christmas, she would get me Matchbox and Hot Wheels. I had every Hot Wheel from the first year and the following five in various colors. My younger sister decided to sell them at a rummage sale she had, and never even asked me. I still have 15 of the original Hot Wheels first couple years and 30 Matchbox from the earlier 60’s. At one time long after this, I had about 2500-3000 die cast and unbuilt models, mostly Mopars in 2 display rooms in my basement. I sold most of them when we moved here. Knowing I wouldn’t have the room to properly store or display them. One guy from Chicago bought all of them. I still buy the unique limited editions once in a while. The gear head thing, starts young.
