The total mass was 381.69 kilograms or 841.6 pounds. It was delivered in 2196 original samples at a cost for the Apollo program of 24 billion dollars or 28,500 dollars per pound. By 1975 this had been split into 35,600 samples. 5 kilograms were consigned to sample displays in museums around the world for public viewing and even touching! A total of 5.1 percent or 19.3 kilograms have been allocated for scientific study, the rest is archived untouched for posterity. About 1.64 kilograms ( 3.6 pounds) were destroyed in laboratory testing.

The Soviet Luna 16 and 20 missions returned a total of 130 grams to Earth from the Mare Fecunditatus region.

These rocks are not all anonymous. Some are well known to the geophysics community by name:
