color me skeptical, but how the hell do they know this came from the moon and not one of the billions of other stars, planets, comets, etc. in the universe ? more importantly how was it ejected from the moon with enough force to escape the moon's gravity ? maybe some kid with a giant slingshot ?
12-pound lunar meteorite sells for more than $600,000

12-pound chunk of the moon that fell to the Earth as a lunar meteorite has been sold at auction for more than $600,000.
Boston-based RR Auction announced Friday the $612,500 winning bid for the meteorite, composed of six fragments that fit together like a puzzle, came from a representative working with the Tam Chuc Pagoda complex in Ha Nam Province, Vietnam.
RR predicted it would get $500,000 at auction.
The meteorite was found last year in a remote area of Mauritania in northwest Africa.
It is considered one of the most significant lunar meteorites ever found because of its large size and because it has "partial fusion crust" caused by the tremendous heat that sears the rock as it falls to Earth.

The moon gets hit all the time. The force can certainly bust off a piece and send it into space.
Since we picked up moon rocks on the landing, we have an idea of composition and metalurgy.

true but lots of planets have moons, Jupiter has 67 and Saturn 62.
unless they have samples from all of them to compare they
don't know for sure. it could also be from one of the millions of
comets running around out there.

The moon has a unique composition, as compared to moons of other planets, because it is an old chunk of the Earth. The mineralogical composition of other planets and their moons can be determined by remote sensing (satellites, lasers, etc.).

Don't even need "samples." Spectroscopy can be used to determine the chemical composition of distant bodies in space.

Not only did they pay 612,000$, but the damn thing is broken...
