peter chaoGil,
You brought up an interesting point. Sometimes it depends on the numerous ways a card can fit into a collection. Look at a popular card like the '52 Mantle. You need the card if you collect '52 Topps. You need the card if you collect New York Yankees. You need the card if you collect Hall of Famers. You need the card if you collect guys with significant World Series records (holder of most home runs in World Series). You need the card if you collect 500 home run hitters...on and on.
