<p>[QUOTE="SPP Ottawa, post: 1562696, member: 39508"]Here is a recent Canadian example - this particular coin contains 80.28% Cu (RCM specifications are 75% Cu - 25% Ni). I am not sure if I have enough posts to allow anyone to contact me - but if anyone is interested in a copy of the paper I published on 'brown nickels' and alloy mixing errors in The Canadian Numismatic Journal, drop me a message on my 'home page' here and I can send a PDF out to you.</p><p><br /></p><p>[ATTACH]212031.vB[/ATTACH][/QUOTE]</p><p><br /></p>
