Editing to Opinions- please be mindful of the categories

I would probably choose normal-looking objects that I would still be able to recognize in case I needed to find it, something like a pen or an interesting rock

I would, in all seriousness, make it some ordinary object(s), and bury it/them in the middle of the sea, so no one could ever find it. Voldemort was foolish in choosing such sentimental hiding places.

The sword of Gryffindor. somehow he can get it, using Peter's help or something idk. Anyways if he does make the sword a hurcrux the only way to destroy it would be to get a basilisk's venom, so I would just sneak to hogwarts and get all the venoms out of the basilisk's mouth. and yeah. other than that. just make the most random object in like a random far away country. I really have no idea why he kept them all in England
