but in order to see what cards are in there,you have to open them.....
Could be an expensive card in there. How much you willing to pay to find out?
nothing because there is a greater chance there aint shit in there.....but back in the early 90's a buddy of mine bought 10 different card packs and opened them...one of them had a Bowman Leaf Frank Thomas's rookie card which was worth at that time $100.00 .....so you never know....

.
Back then we paid $1 for a pack, never opened it and said one day we could charge $20. Today id say if there was a chance an expensive card was in the pack someone would pay $100. And it's not like all the other cards are worthless. It was 35 years ago. Those cards are old. And it's not like there's only 1 card in the set that's expensive.
And clearly you aren't rich or a crazy card collector.
