I collect arrowheads, old coins and cool stuff found while metal detecting. I have a stamp collection but I stopped collecting back when they started making so many different stamps every year that nobody could keep up with them. I used to collect minerals, matchbooks, matchbox and hotwheels, star wars stuff, coins, old fishing lures, boy scout memorabilia, antique automobile advertisements, old toys and anything else I could find. I had to narrow it down a bit and focus on a few things I really like and let the rest go.
