if I own it, not rare -- if Leon owns it -- very rare
If you make 50 of a card and only 25 people want it (manufactured scarcity) -- you have an easy card
And supply and demand -- the rarest and most expensive stamp is a postally used dirty and written on 1c british guyana stamp which wikipedia (and we know how reliable the internets are) says is locked up in a bank vault because the owner died while in prison.
My goal is the find of Fans Card including Cobb and Ruth
