That notch, if that's what you're referrimg to, is to locate the back with the protrusion on the main case. I'm not really up on the whole 'Gold Fill' process, but edges like this and corners usually show the wear first, and any seams. The use of the word 'Warranted' denotes Gold Fill.
All these corners seem to show the underlying base metal, or are these the 'cuts' you mentioned? That is, the edges being cut and bent and forming seams. Usually these are stamped out, but again, I've never seen the process or any mention of it.
