Colorado's missing $5 million moon rock? Turns out an ex-governor had it.

Gov. John Vanderhoof says that he has a moon rock given to the state in 1974, which officials only recently realized had gone missing.

A former Colorado governor reportedly has a moon rock given to the state in 1974.

Gov. John Vanderhoof tells Denver's KMGH-TV that he has the rock, which officials only recently realized was unaccounted for. Vanderhoof says the rock is displayed in a golf-ball sized acrylic button on a plaque in his home.

The rock is valued at $5 million on the black market and few even realized it was missing until a college student began searching for them for an assignment.

Another set of moon rocks collected in 1969 was found in storage at the state history museum about a decade ago. They're now on display on the third floor of the state Capitol.
