What is the rarest Tomy/Plarail/TrackMaster item you own?

I don't know Vio, different bidders have different ways of considering the rarity and putting their money in. Yes, cost is a determining factor of rarity. In my opinion and your opinion since your first post, we are only considering the mere existence of the products so I think we are best sticking to that. Smart idea about using the distribution amounts.
