In regard to the "Trade Stock", the pictures accurately display what I may or may not have available for trade. I am continually adding new crowns to the trade stock and caps are continually being reserved for collectors who have previously contacted me. Additionally, before any crown is sent to a collector it is matched to my collection. If for some reason it is not in the collection it will be added and an alternate crown can be requested. Also, I trade crown for crown. This does not mean an unused cap cannot be traded for a used cap, or plastic for cork, what it does mean is that crown rarity will be considered. It is unlikely I will trade a rare 30-year-old plastic lined crown for a recently issued micro.
One thing that should be mentioned however are my current trade interests... many collectors will see caps here that they are interested in. I however am only interested in US beer crowncaps, crowns from set/series (worldwide, (all products, no undersides)), and crowns with images of Cherries, Owls, and Bats. I understand this makes it very difficult for many collectors outside of North America. If there are caps here that you ultimately are dying to add to your collection and you do not have items I seek, contact me directly and maybe we can work something out. If there is something specific that you are looking for from North America, again, feel free to contact me directly. I am displaying everything I have available; I expect the same courtesy (through website pages, image hosting sites, scans, etc) during our trade discussion.
