Hi guys, I recently ordered a Pikachu's New Friends Blister Pack. The pack came today and as soon as I saw it I knew something was wrong...

As you can see from the pictures, there are lines down my unopened cards. These are not on the box and it looks like these are error cards. The line looks black but as soon as I turn it to the side, it disappears suggesting that there are lines of the holo overlay missing.

Could anyone tell me what's up with these? I know that error cards can be worth money so I want to know before I send these back.

Thanks
