I see there is a demand for gold foil cards. (not much, before game launch, but there is) Just today, the 24h volume is around $1K and around 110 sales made, that means average price is around $9.

How I see, people are mostly buying up the cheap regular ($0.25) cards and the most expensive gold foil cards (best players, coaches). I do the same, next to selling plenty. There are plenty cards what are probably under (and over) valued. Some guys even buying up the cheapest gold foil cards.
