I'm one of those people who love to collect random crap. If it interests me and I have the money, I will contemplate on getting it (eBay is my guilty pleasure). Some of my more notable collections are coins (and sterling silver stuff along with that), hot wheels cars, and Lego. It might be strange to some people that an adult would collect toys, but I use them more for display or reminisce than to play with. Lego I build sets time to time, but I really love the minifigure releases. Turns out there's a market for these toys as well, and having some of them now means I can potentially resell them in the future. I use some money generating apps on my phone to gain cash over time which I then use to buy things for my collection. So even though I spend quite a bit of money on these things, only a fraction of it is from my own personal expenses. What do you collect?
