Here's an interesting coin from 1942 as it should be made of either Nickel or Tombac however this one is minted on a planchet made of cupro-nickel. An ERF revealed the composition of Cu 76%, 23% Ni and trace Fe,Mn and the weight is 3.17 grams. When compared to a regular 1942 five cent coin it's considerably smaller in diameter and thickness. After searching I can find no known records of the mint producing any coins for any country using a cupro-nickel planchet at any time prior to and including 1942. Does anyone think this could have anything to do with the war efforts to conserve nickel in 1942? I'd appreciate your thoughts. TIA Edited to add, It was discovered mainly because it's also non-magnetic. Cheers, Bill      Edited by Hounddog Bill

Same properties (and size) of the 1942 Cu-Ni cent that Smallcentguy has. His coin was written up in the CN Journal in Henry's error column - April 2010 issue, p. 174-175.

Interesting, I never knew this coin existed. Here are some possibilities: 1. The mint were testing several alloys to reduce the use of nickel and this may be one of the test coins with the composition of cupronickel. But was rejected in favour of tombac and was either released into circulation accidentally or smuggled out by a mint worker. 2. I highly doubt this possibility, but maybe the Royal Canadian Mint were making nickel coin blanks for the US mint or another foreign country but a portion of them somehow entered the Canadian nickel coin blank supply bin. 3. A counterfeit, but I highly doubt anyone counterfeiting such coin and the details look well struck. It is one heck of an interesting coin, and the details are great as well. |

The RCM minted a 5 centavo coin for the Dominican Republic in 1937 using copper nickel planchets. The weight (5.0 g) however, is not even close to your coin. They also minted coins for Jamaica in 1918 using copper nickel planchets. http://www.coinscan.com/for/foreign.html) |

It seems to me that it is an error coin, struck on a blank intended for another coin from another country. The British Royal Mint was notorious for these sorts of errors in the years before and after the transfer from London to Llanstrissant in Wales, at a time when they were also executing orders for circulating coinages for many countries. That sort of circumstance may well provide the explanation for the existence of the numismatic curiosity in this thread. |

That worked. Great site for sure.
I'm familiar with this site and I had used it quite some time ago. If these were listed when I used the site then I must have missed them or I eliminated them because of the weights.
It's been ten years or more since I've looked into the coin.
Cheers, Bill

This is a link to smallcentguy's 1942 one cent coin that is minted on a planchet the same as this one. It's the coin SPP is referring to in his reply in this thread. I just thought it would be of interest to connect the two. Cheers, Bill http://goccf.com/t/145821&SearchTer...pattern?Cent |
