London: A Quran written in 1203, believed to be the oldest known complete copy, has sold for more than $2.3 million at an auction.

The holy book, which had been estimated to sell for up to $715,000, fetched $2,327,300 at Tuesday's auction in London, Christie's said.

That was a record auction price for a Quran or any type of Islamic manuscript, the auctioneer Christie's said.

A nearly complete, 10th-century Kufic Quran, thought to be from North Africa or the near East, sold $1,870,000.

Both were offered for sale by the Hispanic Society of America, and were purchased by trade buyers in London, Christie's said.
