My boys and I were into baseball cards for a few years, as well as a guy from work and I. We fell out of it mostly due to the over production. Every year there would be more and more sets, and super premium cards. It was tough to find where to spend our money. Now, I will search eBay for auto/game used cards of my favorite players.
Wow, good for you. I have thought about that briefly, but we can't wrap ourselves around it enough to commit.
I was big into action figures for awhile. Star Trek, Simpsons, Marvel Legends, and others. As the prices went up, I drifted out. I will probably donate most of my stuff to the local Shriner's hospital when I retire.
