Hello Greg C. and All,

The self pairing issue comes up at least once a year. I agree that a single number would be best for all, but there are too many problems with that model. In the original question Greg C. asked with NWA 1877 as an example, as one of the original co-owners of the NWA 1877 material, I believe in keeping the TKW's and authenticity of the material as accurate as possible. The NomCom has laid out specific rules which should be followed as Jeff Grossman very clearly pointed out. About a year after NWA 1877 was given the official number, on one of my near-monthly trips to Morocco at the time I bought more of the material that surfaced. Instead of selling it as "NWA 1877", I followed the rules and supplied a 20-gram type sample to scientists and paid the lab and scientists their fees to have it officially classified. I received a new number, "NWA 5603". In my eBay description, I mention the pairing to NWA 1877.

An example to illustrate it is not a good idea to take the word of someone selling "self-paired" material, lets take the case of the Martian NWA 2975. As Jim Strope pointed out, "NWA 2975" was a single stone, yet other small complete individuals are being sold as NWA 2975. Another case where many of us did the right thing and supplied the full type sample and received a pairing NWA number. There was a great case why we should not cheap out with hiring a competent lab and providing the required full type sample. In this particular case, a well established meteorite dealer was trying to sell a somewhat large Martian stone as, "...being paired to NWA 2975..." As it turned out, that single stone WAS NOT paired to NWA 2975 and it was through the efforts of competent scientists and others who helped to correct that wrong to the delight of the dealer offering that supposed "pairing". It now has an Official meteorite Name/number and now it is accurate and different from 2975. Bottom line, it does not pay to cheap out with getting stones authenticated and paired if the material actually is.

As to the case of NWA 5480, I first got that material and had the scientists do their work to reveal the amazing components of this new meteorite. The people who I purchased the material from in Morocco sent me a few more stones they were sure were paired to it. After receiving these few stones, it turned out one of the stones WAS NOT the same as NWA 5480. This goes to show that self pairing not only hurts the true nature of the material, it makes it to where collectors become unconfident in buying from people who make self pairing claims. The stones that were paired were added to the TKW of NWA 5480. Sometimes it is simply an accident that the 'other' material is thought to be the same, other times it is not this way. Either way, it is the responsibility of resellers to do the right thing.

So, lets keep it real and do the responsible thing for the sake of accuracy for both the science and to keep collectors confident in what they are purchasing. As new meteorite collectors/dealers enter the arena year after year, it is up to them to do the right thing. You can not simply take the word of someone who claims, "This material is for sure the same as 'NWA 1877, 2975, 5480' "... and the list goes on.

As Adam coined several years ago, "When in doubt, check it out!"

I wish everyone a prosperous and accurate year for collecting, finding and selling meteorites!

Best regards,
Greg
