(if you wish to retain ownership, ask if they would accept the artifacts while owned by a revocable trust you have beneficial interest in, "on loan from" the trust; if this is not important to you, you can simply gift them to the museum)

The issue with this is that you lose control once you give them away, no matter what.

A former landlady of mine donated the historical motorcycle her father once owned to a reputable museum under the condition that they keep it on display. Couple of years later by mere coincidence she got wind that the bike was amongst items the museum was about to auction off. She bid it back for a lot of money.

Moral of the story is that once you give it away it is out of your control. It is certainly good to be conscious who you give it to, but in my opinion it is not worth sweating over it.
