When I visited an arcade, I found a gold rare card found there, the people might don't know how good the card is. I tried the card and it is usable. Why the people throw the card just like that? Maybe because he or she don't know about the card or maybe to let someone get the card when it is found. Take note when you throw away something at an arcade do not carry a card instead, or you will throw it by accident. Keep your cards in a binder, or a box where it could hold your cards.
