Note, these Lunar Sample Displays should not be confused with the Goodwill samples (
70017) - that were distributed to nations around the world.
collectspace have an
article about it with a request to try to track down more of the current locations of the presentation items.
Te Papa in Wellington NZ have a piece of the Goodwill sample along with a flown NZ flag:

I recall this being on display at the old Dominion Museum in Wellington. These days the item is in storage.
