I used to be an avid Wacky Packages collector, and purchased a set of the 2007 prototype pins when Camera & Stepper auctioned them off on eBay. They have been sitting in a drawer for a very long time, and can't really find info on them anywhere online. Are these still collectible/something people are interested in? I'm probably looking to sell these now, and was wondering a ball-park range which I could list these for, as I have no clue what I even paid for them. I attached a couple pictures of the pins. Thanks!
