Donate them to a museum. Most public museums will allow family access to donated items for viewing. Not sure if you can retrieve the items permanently at a later date if you wish.

My family were wainwrights and coach builders and we donated a full workshop of tools to a Cobb and Co museum and, on request we have taken younger generations up to go through the different items and talk with an expert about their heritage. There’s even a working workshop there where they can see how different tools could be used. They do restorations and maintenance old working coaches and teach that as a set of trade skills still. It’s pretty cool.
