<p>[QUOTE="Bill in Burl, post: 985889, member: 23692"]It looks to me like any other '59 that has come into chemical contact with any number of possible cleaning agents. As I have put in other posts, the only way to tell for sure (and what the "experts" will do) is to take it out side or at a window into natural light .... no artificial light. Gently scratch the edge with a diamond or piece of glass (no metal). Then look at the color of the base metal that lies under the surface tone. Even bronze in bare metal looks a little yellow. There are no specific Obv or Reverse markers that will tell you a brass one because the current examples don't show similarities. It is my opinion and that of other Vicky experts that there really were no real "brass cents" made on purpose..... they were the result of alloy mixing errors in the making of the planchets. The specific gravities and the small percentages of zinc and tin are so close, it takes very little to cross the threshhold from bronze to brass. Too long in the mixing pot, impurities in the core metal, or the first pour from the mixing pot all could result in "brass" resulting rather than bronze. This was the late 1850's and the Royal Mint had worked only with copper before. The planchets for the 1/3 thinner (but same dia as the Brit halfpenny) Canada large cents were special order because all previous Brit coinage was just copper..... and it was a massive 10 million piece order. I've looked at 10's of thousands of Vicky large cents and I don't think that yours is brass.[/QUOTE]</p><p><br /></p>
