Vienna: The world`s largest gold coin, weighing 100 kg with a diameter of 52 cm, was sold for 3.27 million euros (about USD 3.99 million) at an auction here.
Spanish dealer Oro Direct offered the price and became the owner, Xinhua reported.
Six bidders were registered for the auction. Oro Direct offered the bid in a written form, while the other five applicants participated through telephone.
The coin was originally owned by Auer von Welsbah (AvW), an Austrian investment management company, which went bankrupt in May 2010.
