I have well over 100 Transformers (probably closer to 175 at this point to be honest)
Tin Toys are a lot harder to find as they're really only sold in antique stores (for the vintage ones) and small, privately owned toy stores, which are few and far between these days. So I only have about 8 or 10 of those, but I did find a website that sells a LOT of them in the fall, so I'm saving up to buy a bunch at once and save on shipping.
I love to collect old coins, simply because it's fun to imagine where it's gone and been over time. The older it is, the more I want it.
My oldest coin is around 900 years old; it's a gold trading piece from Afghanistan that I got for Christmas. 3nodding
I'm starting to collect energy drink can tabs, and books. xP
But I also collect random little objects to add onto jewelry. Kinda like what "Kandi Kids" do by adding little small stuffed toys, or buttons, or bells, ect on their "kandi". xP
I actually got into that by making some of that stuff. It's really fun.
