It doesn't take dishonest people too long to figure out that a common meteorite purchased at a show can be planted in some new location where a new find would bring a lot of money. I don't know how this can be prevented or avoided, but it's pretty obvious that dealing with people you know very well is a step in the right direction. Just four days after Jack Schrader announced his first finds of the latest Arizona fall, I got a phone call from a guy in Southern Arizona who claimed he had a new Arizona meteorite he had found three and a half years ago and he was going to sell it at auction. He wasn't clear about what kind of auction he intended to use, but I got the idea he was going to offer it to whoever offered him the highest "bid" over the phone. I get so many calls like this I was going to tell the man I wasn't interested but decided to ask him a few questions. His answers were typical and somewhat amusing. The find location was somewhere in Southern Arizona, but he wouldn't narrow it down any more than that. He claimed the first test he had done was a fire assay. Hmmmm, seems like a weird test for a meteorite. Next, when asked what the classification was, he said it was an anomalous achondrite with 28% nickel. He had sliced the nearly 2 kilo stone and had a ~750 gram slice that was full of metal veins. To get the metal to show up better he had etched the slice with pure nitric acid. as I asked more questions, his answers got more evasive. Sure hope I didn't miss out on a good deal, but my common sense told me to take a pass. There's nothing to prevent someone from offering an inexpensive NWA meteorite as a new find. As long as they stick to their story it's near impossible to prove them wrong. It has happened to me a few times so I'm guessing it has happened to other List members as well. Is there a solution to this? I guess only time will tell.
