29,050 Antarctic meteorites divided by 5 pairings each since every fragment is counted equals 5,810.? If every fragment were counted from Northwest Africa, the total meteorites found would easily exceed 1,000,000.? NWA is the number one producer of meteorites by weight, number and rare finds, all accomplished in less than two decades.

Erik,

This would be a nearly impossible exercise to do.? What I can say is this: There are 29050 classified Antarctic meteorites in the world's colletions, and 12664 classified non-Antarctic meteorites.? If we assume that all of the Antarctics are government-collected and most of the non-Antarctics are privately collected, then by number of named meteorites, ~30% were privately collected.? If you do it by mass, it is all dominated by the large irons, and then you have to worry about who collected each one.? If you do it by numbers of individual specimens, I have no idea... this tends to bias the answer toward observed large showers like Holbrook.

Tens of thousands of desert meteorites, especially NWAs, are unclassified, and will not be classified any time soon.? But these tend not to be "acquired material [in] universities and museums."? So we probably don't have to count all of them (even if we could).? But there are nearly 9000 unclassified Antarctic meteorites in institutional collections which might be counted.
