While other "goodwill Moon rocks" commemorative plaque displays were reported lost or missing by several recipient countries, both the Netherlands Apollo 11 and Apollo 17 "goodwill Moon rocks" commemorative plaque displays are in the country and accounted for. However, in 2009 the Rijksmuseum of the Netherlands declared that the "goodwill Moon rock" it had received in 1992 from the estate of Netherlands Prime Minister Willem Drees was bogus. This "Moon rock," which had been exhibited for more than a decade on a gold-colored piece of cardboard, weighs 89 grams (3.1 ounces) – far larger than the 1 gram piece of lunar basalt 70017 affixed to the Netherlands Apollo 17 lunar sample display. Testing of the Rijksmuseum "Moon rock" in 2009 showed it to be a piece of petrified wood, likely from Arizona. The Rijksmuseum had insured this "Moon rock" for ƒ100,000 (€50,000 [$85,000] in 2012 currency) upon its receipt.
