I was watching those morons on hard core pawn (not pawn stars but a horrible knock off of it) and they had one of those guns to see if a samurai sword was real, they shot it and it showed like 96% iron, 2% carbon, then trace amounts of nickel, manganese, chromium, copper, etc. So these geniuses say "Nope, it's mostly iron not steel, so we're not interested!" :rotflmbo:Whenever this subject pops up, I always feel blessed to have an X-ray fluoroscope at my immediate disposal. I've used it several times for my LCS when he had a client challenge the quality of smaller bars in a deal. Although the penetration isn't enough for large bars, it is enough for smaller bars and coins, making it a great tool when a client of his is afraid to buy a numismatic for fear that it may be a fake or not gold. He always tosses me a couple rounds for the trouble.
I once did forty quarter ounce gold eagles that were kind of beat up, which is very, very unusual, seeing that most people baby their eagles and keep them in the freaking tubes or in individual caps. For whatever reason, whoever sold these babies to him brought them in a very small Crown Royal bag loose like a sack of dimes and they were all banged up. He was selling them at a premium that was significantly lower than usual so it was a good deal for the buyer, but he was suspicious as hell. My guy called me and I came down the next afternoon and shot the whole lot of rounds. They were exactly on point. The buyer was impressed as hell, because I used his "lucky" gold piece he wore around his neck to calibrate with, a quarter ounce gold eagle in a bezel.
Most large scrap yards have a Niton gun [or similar] that can be used to shoot a coin/round to see if it is real. Remember though, it can only shoot so deep. It is good for the smaller rounds and bars, like up to one ouncers.
YouTube videos would be helpful....
So how do I get this idea out there so people can see it?
It couldn't hurt, but pmbug.com occupies a small, cozy corner of the internets. There are other sites that get much more traffic (and correspondingly charge more for advertising)....
Do you think it would be worthwhile to advertise on this site?
