Free Shipping
Product Overview
While it is extremely rare for a Canadian coin to be struck on the blank for a different Canadian denomination, it is even more rare for a Canadian coin to be struck on the blank intended for a coin from a different country. This 1979 Canadian one-cent coin has been struck on a smaller and lighter blank intended for New Zealand one-cent coins, which were also being produced by the Royal Canadian Mint in 1979. The coin has been independently certified and encapsulated by the Professional Coin Grading Service with a grade of MS-64 Red.
As a result of modern technology and excellent quality control at the Royal Canadian Mint, major error coins are rare in Canada. But with the large volume of coins produced for circulation, a few error coins will occasionally escape scrutiny at the mint and make it out to the banks and into the hands of collectors.
One of the rarest and most sought-after of all possible error coins results when the blank (or planchet) intended for a coin from a different country is used to strike a Canadian coin of a different size, weight and metal composition. A regular 1979 Canadian cent has a weight of 2.5 grams and is made of nearly pure copper, while the New Zealand cent has a weight of 2.07 grams and is made of bronze (with a greater alloy of tin and zinc).
How does a wrong planchet error occur?
In some processes at the mint, blanks and coins are moved in large tote bins. The tote bins have sloped bottoms which act as funnels to allow the bin to empty when a sliding trap door is opened. On occasion, a blank or coin can remain stuck in the tote bin and escape unnoticed. The tote bin may later be used to transport other blanks, and the trapped piece may be dislodged and mix with the rest of the contents of the bin. If the wrong blank is fed into the coining press, the resulting coin will be a wrong planchet error. Only an extremely small number of these errors escape mechanical and visual inspections and make their way out of the mint.
