Smallcentguy Pillar of the Community Canada 1984 Posts	Posted 04/17/2012 08:09 am I know little about metallurgy, but in a previous post on a similar topic the member Ugly suggested this phenomenon was caused by high temperature heat treatment. At a high temperature, the copper can be apparently turned to brass. He said you could make such a coin by placing a regular cent on a high temperature wood stove. Alternatively you could ask SPP if he would do an XRF analysis on it to determine the metal composition. Report this Post to the Staff
kitsy Valued Member Canada 182 Posts	Posted 04/17/2012 08:36 am no RCM logo.......will try post a few pics later..........still can't figure how high temperature treatment with the small amount of copper over zinc would produce a metalliac looking coin..........cheers Report this Post to the Staff

Anytime the Staff sees a topic title with just a question mark for the entire title you can rest assured it will just be deleted. We are growing weary of clarifying titles.
