I am a collector of collections, or a hoarder not sure which.
I collected Sports Cards as a kid, everything from Baseball, Basketball, Football, and NASCAR. I also have my father's card collection, bunch of old farts like Carl Yestremski, and Mikey Mantle.
Moved on to comic books in my teen years and still have a sizable collection.
Through my years growing up I have also built a small gun collection of around 15 guns. I may shoot my glock every couple months, but for the most part they sit collecting dust apart from deer season.
My nerd persona collects lego star wars sets (about 15), as well as collectors editions of my favorite video games and random figurines.
Most recently i've been spending my money on home theater gear. Just upgrading a piece here and there.
