The vast coin collection of a Danish butter magnate is set to finally go on sale a century after his death, and could fetch up to 72 million dollars (£57.4 million).
Lars Emil Bruun, also known as LE Bruun, stipulated in his will that his 20,000-piece collection be safeguarded for 100 years before being sold.
