Likely it will be purchased by a museum or library and treated with the appropriate care.
Not in my experience. They are usually lent indefinitely to museums, though.
The museum then has the burden of insuring the item and you can (if structured correctly) get a tax deduction equivalent to reasonable rent of the item (depending on jurisdiction).
That way, you can safely store the item, get a tax deduction, and then, as the item (presumably) appreciates, sell it later.
It also helps the value of an item to say “on display at XYZ museum for years 2023 to 2033”.
