How can I make a distinction for PS4 games?

I want to sell a couple PS4 games, but I want to avoid having problems with a buyer trying to switch out the games for a broken/fake copy.

The only detail I noticed is for Fallout 4 the last copy I sold had a tiny white spec on the art cover that I notice isn't there on the other cover.

That's all I'm going by but I feel like it's not enough proof. Is that really my only option?
