This is a very unusual "Mule" with the obverse of one country and the reverse of another. The errors were restricted to a production batch of 100,000 coins destined for New Zealand that had been made on January 18 -19, 1967. The Bahama die was used in 1966 and no 1967 Bahama cents were coined. It was paired with a New Zealand two cent die. When these were released there was an international furor over the error. The Royal Mint paid for the coins to be retrieved from circulation. This meant manual sifting and sorting. 60,000 of the errors were found, mostly in the Wellington region. These were melted down in Auckland. Concerns flared in Britain as the scale of the fiasco emerged. The Chancellor of the Exchequer feared the Royal Mint might even lose New Zealand as a customer. A six-month investigation suggested that supervision processes were sub-standard. Security was also apparently minimal. However, the error should still have been found before the coins were shipped.
