Say I am selling a pack of trading cards, and there are 5 cards inside. Four of these cards are basic cards, but the last card has a 1:10 chance of being a special insert card.
Does the fact that the special insert has a 1:10 chance of appearing mean that it is ten times as valuable as a base card?
I understand that value is almost entirely subjective, so I suppose this is a philosophical question more than anything else, but I'm also not really an economist so I don't know if there are any axioms around this.
