Does not affect the coin or the integrity of the holder, just the stacking edge corner. You can see it in the first and second pictures. These are tougher to find in the circulated grades.
This coin gets pricey as you reach the higher grades. Check out the extreme close-ups of the actual coin. Nice coin for you dollar collectors.
