Bought my first STH without even knowing

I decided to go hunting on the last day of the year at different Walmarts and Targets but had no luck finding anything. Then, I went to a Dollar Tree, and they had just restocked cars from 2023, 2024, etc. I bought two Porsche 935s and some other cool cars. Once I got home, I noticed that one of them was an STH! I also found some really nice cars.
