Looting Matters has been monitoring the sale of Egyptian antiquities at Sotheby's New York since 1998. The total for all Egyptian lots from 1998 to 2013 is just over $77 million (with over $383 million) for antiquities. The highest year for Egyptian lots was in 2010 with a total value of over $12 million.
So a single statue selling for the equivalent of $27 million is a third of the total sales of Egyptian antiquities during a 16 year period.
Christie's New York has sold $225 million worth of antiquities (not just Egyptian) over a 15 year period (from 1999 to 2013). There were only two years when the total sales were worth more than $27 million: 2010 worth over $42 million, and 2011 worth over $38 million.
So this is an exceptional price for a well documented sculpture.
