Today I bought the set with all 5 different covers. I got 1 out of 2 that were at my shop. Without thinking I opened two of them, one to read, and the other had something on the inside that I removed. Will it still be valuable in the future? I am somewhat new to comics, so I thought that something like this will be valuable in the future.
Edit: I did read it cautiously so that nothing would be bent, messed up or anything.
