2,196 samples, each with a record of where it was found.
NASA reports 382 kilograms from six landings, divided into 2,196 original samples: rocks, soils and drill cores. The Lunar and Planetary Institute’s atlas lets anyone follow individual samples from surface photograph to laboratory slice. [1][2]
The meteorite idea runs into a timing problem. The first meteorite recognized as lunar, ALH 81005, was found in Antarctica in January 1982, and it was identified as lunar partly by comparing it with Apollo samples. [5] Von Braun’s 1967 trip was publicly reported at the time as a study of how to work in harsh places. [6] Meteorites also have a melted crust from entry and show weathering from Earth, which Apollo rocks lack.
Robots do not fit either. The three Soviet Luna sample returns together brought home about a third of a kilogram. Apollo 16 alone returned 731 samples weighing 95.7 kilograms, including a drill core 2.2 meters deep. [4] The Soviet Union received Apollo samples under the 1971 agreement and never called them fake.

Scientists still find surprises. In 2006 a Nature paper on oxygen isotopes in Apollo soil challenged standard models of the early solar system. [3]
