I do not know if it is a correct forum, but I'm looking for an article entitled "World's coinage uses 24 chemical elements" from World Coin News (February 17 1992 and March 2 1992) by Jay and Marieli. Could you share it with me? Thank you.
Not too sure if this is what you are looking for: http://www.coins-of-the-uk.co.uk/pics/metal.html I've attempted to collect coins by various elements: http://gxseries.com/numis/coin_elements/coin_elements.htm
Thank you. I found a sentence in first link: "Additional information has been gleaned from an article published in World Coin News (February 17 1992 and March 2 1992) entitled 'World's coinage uses 24 chemical elements' by Jay and Marieli." and I'm looking for this article, especially I'm interested in Magnesium ("There have been some minor issues - the Jay and Marieli article refers to a 10 pfennig Lodz Ghetto issue.").
Did you ever find that article? I have a scanned copy I can email you if interested. Your avatar looks like the magnesium coin. I've got one like it, and it is much lighter than an aluminum coin would be. The envelope it came in had a handwritten note that said it was made from scrap metal recycled from downed airplanes. I've also read that these coins were made of magnesium-aluminum alloy, or alternatively that there were both magnesium and aluminum versions. So I don't know if mine is pure magnesium, but here's what it looks like. http://www.omnicoin.com/coins/1028020.jpg I am hoping to get my hands on a handheld XRF analyzer soon, which ought to answer some of my questions.
Buying, renting, borrowing, or just visiting? I'd love to get one of those, but as long as they're priced in the new-car range, it's not likely to happen. I see that there's a second-hand one on eBay for $13K.
I can't afford one either, and places I've found on the net that will do rental or let you send in samples for testing also charge amounts I consider to be high, probably because it would take a lot of testing charges to recoup their investment. I happened to run into someone who uses them in her work, and she said she'd let me visit her lab next time one comes in from the field. It may be an idle social promise however, as I've never heard from her since, despite my reminding her via email of her offer. I would think a decent sized university engineering department would have one. Or maybe a scrap recycling buyer, or a big jeweler. Haven't pursued those yet.
