Just curious as to what technically makes a deck of cards or certain card Rare, does anybody know ?? Is there a number amount of production that wants it hits a certain number it becomes rare ?? I think that word is totally over used nowadays it's almost in every deck of card listing how can a deck of cards be rare and $4 a deck ???? Wtf ??? In my mind when I hear something is rare I'm assuming is probably very expensive because I thought rare means is extremely hard to find. Someone please fill me in.
