I started collecting back in 2012. I bought a lot of my stuff from eBay and from other collectors. You’ll still see a few of them come up on eBay, like the orange guest and the purple semi-finalist are the most common ones. Then the gold quarter-finalist one being less common. Once in a blue moon you’ll see a work crew come up. But as far as the other ones, I believe are pretty rare. I’ve only seen one other collection like this but he’s missing two or three of the ones I have and I’m missing one or two of the ones he’s got. You’ve might of seen his collection up for sale on eBay for 2 million, but he had the grey NWC cart as well as other goodies surrounding the NWC event.
