FlyingXS Posted July 21, 2014 Share Posted July 21, 2014 I have been reading how people make Mokume from US Nickels. I'm just wondering if any of the Aussies have tried this with our local AUD currency??? Quote Link to comment Share on other sites More sharing options...
781 Posted July 21, 2014 Share Posted July 21, 2014 Us 5 cent is 75% copper and 25% nickel and to make mokume you need a layer of copper or brass between to have contrast. Our 25 cent and 50 cent pieces are already layered that way and is what is used mostly for quarters mokume. Quote Link to comment Share on other sites More sharing options...
FlyingXS Posted July 21, 2014 Author Share Posted July 21, 2014 It appears for the moment that ours is the same. Australian coins [1] Image Value Technical parameters Description Date of first minting Diameter Thickness Weight Composition Edge Obverse Reverse 1c(no longer used) 17.65 mm 2.60 g 97% copper 2.5% zinc 0.5% tin Queen Elizabeth II Feathertail Glider 1966 2c(no longer used) 21.59 mm 5.20 g Frill-necked Lizard 5c 19.41 mm <1.3 mm 2.83 g Cupronickel 75% copper 25% nickel Milled Queen Elizabeth II Echidna 1966 10c 23.60 mm <2 mm 5.65 g Superb Lyrebird 20c 28.65 mm <2.5 mm 11.3 g Platypus 50c Dodecagon 31.65 mm (across flats) 2.5 mm 15.55 g Plain Coat of arms 1969 $1 25.00 mm <3 mm 9.00 g 92% copper 6% aluminium 2% nickel Interrupted milled Queen Elizabeth II Five kangaroos 1984 $2 20.50 mm <3.2 mm 6.60 g Aboriginal Elder 1988 These images are to scale at 2.5 pixels per millimetre. For table standards, see the coin specification table. The size and composition of some of Australia's coins may have to be changed because of the soaring cost of copper and nickel. This year, the metal value of the 5c, 10c and 20c coins will overtake their face value for the first time. And the metal content of our 10c, 20c and 50c pieces is now worth more than the metal in the $1 and $2 coins. But anyone who thinks melting down coins could be a clever money-making venture has been warned it is illegal to melt currency and heavy penalties apply. http://www.dailytelegraph.com.au/news/national/coins-worth-weight-in-gold/story-e6freuzr-1111115748072?nk=f1226ad068ebd68e712777e1e4bf9f9a Quote Link to comment Share on other sites More sharing options...
Chinobi Posted July 22, 2014 Share Posted July 22, 2014 Most of those should be fair game for use in mokume, DEFINITELY read up on your local laws and regulations regarding destruction, defacement, and 'repurposing' of federal currency beforehand though. there is a clause in the US laws that allows for coinage to be used for "art purposes" as an exception to our ban on recycling/melting/defacing etc. there have been a couple of threads about it previously. im not certain about the one with 6% aluminum though, that might be kind of a wildcard. id test a stack or two with those once you have gotten the process down a bit to see if you can get them to work consistently before trying to source out a large quantity.
