Speaking of guns, looks like the holes on your comics have "exit wounds" on the front cover, meaning the puncture started on the back of the comic. You can tell by the larger amount of paper missing on the actual front cover, compared to the smaller holes on the inside pages. As mentioned above, perhaps the newsstand had a display wall with finishing (headless) nails pounded in to function as "pegs". Each month new copies of the comics were pushed onto the nails at the corner and hung, now on display, till the next month. Then maybe... your OO bought them as at discount because they were old and "damaged"? I can imagine some clever young kid working out such a deal
