How much are space rocks worth?

Answer 1

The Apollo moon missions retrieved about 900 pounds of moon rocks and returned them to Earth. A number of small samples slabbed in acrylic plastic were given by the U.S. to foreign governments and officials.

Very few "moon rocks" are in the open market; every one that the FBI learns about is confiscated and returned to NASA.

Meteorites, rocks which have fallen from space and landed on Earth, are relatively plentiful and are the property of the finder, or of the land owner where it falls. The price depends on the size and quality of the specimen. Some of the smaller ones are a few dollars, while a friend of mine paid $2,500 to purchase a 9-inch diameter slab of a stony-iron meteorite that had been sliced and polished to a mirror-like finish.

Answer 2

The value of space rocks varies widely depending on factors such as rarity, size, composition, and provenance. Some meteorites can be worth as little as $1 per gram, while rare specimens can fetch prices in the tens or hundreds of thousands of dollars. It's important to research and authenticate any purchase to ensure its worth.
