Is my CGC case damaged???

[vicdoommd-migration]

I have 19 CGCed comics and 15 of them have a 4 inch smear or mark on the middle of the right lining of the case. Is this normal? What is this? This happens to frequently to be a random mistake. Is this normal or is this a "crack in the case"? Does this effect the value? Please let me know, thanks.

This mark is from the mold for the case and is more visible on some cases than others. As long as the four corner posts of your outer case are still in tact then your comic is OK.
