Thank you all!
I'm still a bit conflicted but I think I might perhaps keep them. Kind of feel bad getting rid of them.
My original plan was to keep only circulating coins (proof or otherwise) but maybe I'll rethink my position to keep whatever has legal tender, even if commemoratives, as opposed just medals (I found many of those too, either issued by the mint or private companies).
I'm not a big fan of those bulky and made to look nice packaging. They are often low quality (some of the 40-50 years old boxes are really in bad shape, definitely not archival quality, breaking apart). Plus they are all different in sizes, take up so much space. Not my thing

At the same time though I feel bad removing the coins from the original packaging..
