This is 1965 X-Men #15, CGC 4.5 Sentinels Appearance. The X-Men invade the Sentinel's underground complex but are captured; Beast is taken before the Sentinel's leader, Master Mold, and has his mind probed; Master Mold commands Trask to make an army of Sentinels so they can take over the world.

Any CGC case may have minor imperfections including Newton rings, scuffs, standard surface wear, or minor cracks. CGC considers these defects acceptable, as do I. If there is any significant damage to the slab it will be noted in My description, and I will not list any slabbed comics with a damaged case that compromises the integrity of the grade.
