World's largest gold coin fetches $4m at auction.

The largest gold coin in the world has been sold for $4m (£2.6m) at an auction in Vienna.

The Maple Leaf coin measures 53cm (21in) in diameter, weighs 100kg (200lb) and is listed in the Guinness Book of Records.

The coin was bought by a Spanish precious metal company on Friday, the auction house Dorotheum said.

The auction had been ordered by the administrator of an Austrian investment group that had gone bankrupt.

ATM type machine which montior gold data and offers gold coins

Its a brain child of a German entrepreneur, Thomas Geissler, who began testing the cash-for-gold machines in his native country in 2009.

The Abu Dhabi debut on Wednesday is billed as the first international foray for Geissler's "Gold to Go" brand.

The ATM-style kiosk in the Emirates Palace monitors the daily gold price and offers small bars up to 10 grams or coins with customized designs.

The unveiling was timed well. Gold hit a record high Wednesday of more than $1,245 an ounce.

Abu Dhabi was chose because of its high-rolling atmosphere and the region's traditional ties to gold in commerce, says Geissler.
