Most expensive stamp collection

According to Official Guinness Records,

The Kanai collection of 183 pages of the classic issues of Mauritius sold for CHF15,000,000 ($9,982,033 / £6,887,052) in a single sale conducted by Geneva-based auctioneer David Feldman in Switzerland on 3 November 1993. The Kanai collection is named after the Japanese engineer-industrialist Hiroyuki Kanai, who collected the classic Mauritian philatelic items that were brought to auction as one collection.
Of the 183 items in the Kanai collection, just four items account for 75% of the total value of the collection (two were unused 'Post Office' stamps).
