Each new card you collect add collection points to your Collection Score. The number of points awarded depends on the card. For the majority of cards, points are based on tier of rarity. Base, Tiers 2-9, Total Performer & Collector Cards are all worth different numbers of points (table below)

However, for cards which are limited by supply - e.g parallels and sequentially numbered cards - points are based on the number of copies available and what it adds to the card score. The score given for a parallel is added on to the base score for the cards tier to make a new total. (e.g a Next Goal Wins #/5 would be worth 10 + 125 = 135pts)

Note that you only get points for the first copy of each distinct card you own, not for duplicates. Since each parallel variant is a distinct card, you do get points for gaining parallels of the same parent card, when they are of different rarities.

Note if you sell your last copy of a card, you lose the same number of points as you received when you obtained your first copy.
