When German troops invaded Norway on 9 April 1940, 26 lorries were loaded with 1503 crates and 39 barrels containing 50 tons of gold ingots and gold coins. This was Norway's gold reserve and was to be transported out of the country. And they succeeded in getting the gold to safety in England 1 1/2 month later, along with the king and the crown prince. The Germans never got their hands on the gold.
Over 50 years later, in 1988, Oslo Mynthandel purchased the remains of the Central Bank of Norway's gold reserve from various banks in Canada and the United States for NOK 100 million. The transaction was mediated by the respected London firm of Spink and Son Ltd. The sale is recorded in the Guinness Book of Records as the biggest coin sale ever.
