Depending on condition, instruments made during Stradivari's "golden period" from 1700 to about 1725 can be worth millions of dollars. In 2011, his "Lady Blunt" violin from 1721, which is in pristine condition, was sold in London for $15.9 million (it is named after Lord Byron's granddaughter Lady Anne Blunt, who owned it for 30 years). It was sold by the Nippon Music Foundation in aid of the Japanese earthquake and tsunami appeal. In Spring 2014 the "Macdonald" viola was put up for auction through the musical instrument auction house Ingles &amp; Hayday in conjunction with Sotheby's via silent auction with a minimum bid of $45 million. The auction failed to reach its minimum bid by 25 June 2014, and the viola was not sold.
