Coin Set With Damaged Cardboard Sheet, Less Value?

Hello, I'm wondering if my coin set loses value if one of its cardboard sheets has a hard crease.

I'm not much of a coin collector(I'm solely into banknotes), but I do own a bunch of coin sets. Most of my coin sets came sealed inside a cardboard sheet. For example, I own one like this, although this is not the picture of my actual set:



Mine has a hard crease on the cover sheet which you can see on the left hand side of this picture. The rest of the set along with the actual coins are in a perfect state. So, does a coin set with one damaged cardboard sheet have less value ?

Thanks
