I like your idea and the model. Although I dont understand any of it, it makes sense that these cards increase in value. Espciall gold foils. I am actively bidding on a couple of these to get good deals or snipe them right away when there are good offers.

But mathematicall I can't follow you here. But that's mostly because I don't speak native english and math... well I can sum up some small numbers in my head. But that's about it
