Yeah, I could see people often losing those if they were little individual gems that were magnetized to the gauntlet. There?d likely be a huge need for replacements.
Though as I mentioned earlier, is there anyone who would want to display him with the gauntlet without all the gems in it? I mean sure if you?re a stickler for screen accuracy he didn?t have all of the gems collected until the end depending on what scene you?re going for with the pose, but doesn?t the gauntlet look more aesthetically pleasing with all of the gems in it? And doesn?t having all the gems collected represent the point of Thanos?
I would think if you were displaying Thanos on his own, having him displayed with all the gems would undoubtedly be the way to go to show him at full power, per se. But even in say a fight scene display, I don?t think having the gauntlet with all the gems in it would take away from the display at all.
