Two of the Island’s rarest stamps could fetch as much as $100,000 each when they go up for auction in London next week.The collectables, part of The Chartwell Collection, will go up for sale on Tuesday at Spink of London, one of the world’s premier auctioneers of coins, stamps, medals and autographs.Philatelists are expected to compete actively for the items and auctioneers predict they could raise between $100,000 and $130,000 a piece.Former postmaster of Hamilton, William Bennett Perot, created the stamps around 1853. There are believed to be less than a dozen left in existence; three are owned by her Majesty the Queen of England.Auction house chairman and CEO Olivier Stocker said: “The Chartwell Collection is, without a shadow of a doubt, one of the biggest “wow” moments we have ever experienced here at Southampton Row.“When the collection arrived in London it was amazing to watch as our specialists turned the pages of what may be one of the finest philatelic collections of our time. Over eighty albums were opened, examined and taken in and it was wonderful to see the faces of the Spink team as treasure after treasure was revealed.“The story behind this collection is absolutely amazing and so unusual in so many ways. It is a great pleasure to be a part of these momentous sales.”Mr Perot was a Corporation of Hamilton alderman and a Member of Parliament. When he became postmaster in 1819 he devised a system that would help him track who was paying for the mail delivery and who was not.He stamped the year date on sheets of paper and sold them individually or in sheets of 12. When letters carried the stamps, he knew they had been paid for.Official postage stamps were not introduced in Bermuda until 1865.The upcoming auction is one of nine that will take place at the auction house over the next 18 months.According to the Spink spokeswoman, it will be the “most valuable collection of stamps ever to come to auction in modern times”.The Chartwell Collection was formed by Sir Cyril Humphrey Cripps and is expected to garner more than $32 million before the last pieces are sold in December 2012.“This is a collection that will undoubtedly rewrite the book for auction records and bring in collectors from around the globe,” the spokeswoman added.Other items to be auctioned off include “Post Office Mauritius” stamps, estimated to be sold for between $650,000 $800,000.
