Not quite the same situation but when my grandparents moved in with my parents, they set aside everything in their kitchen into storage and it sat there for 30 years until they died. I save a few things then set most of it out on table with a free sign and 99.99 percent of it got scooped up quick. A fed ex driver told us they were new to the area and almost everything in their kitchen came from our table.

Nobody wants any of them, they’re old and pretty and also worth exactly zero euros.

You'd be VERY surprised.

I don't think small family heirlooms are the issue OP is trying to address. It's about naitivity of the older generation(s) passing down items that had fit their lifestyle, but their generation made it difficult for the current generation to have the same standards of living.
