We understand that the market for rare, tangible assets can seem somewhat specialist and opaque looking in from the outside. So we created a range of Indices in rare stamps, coins and books to illustrate market movements and market potential for investment-grade material. To make them more robust and transparent, these indices are available to view on both Bloomberg Professional Services and Thomson Reuters.
These are not investable indices in the traditional sense, but take a significant series of fixed, transparent, published data points (coin, stamp or book prices) over time and show the annual movement in value. All the assets selected in the indices are investment-grade material, to provide a snapshot of the investment rather than the collector market (though the two do overlap of course – one of the strengths of these markets is that they are underpinned by collectors rather than investor sentiment).
There are three rare stamp indices, the GB30 Rarities, which tracks back more than 40 years, the GB250, a deeper and broader index with a 14-year history and the China study. In rare coins, 200 investment-grade English coins make up the GB200 Rare Coin Index; finally, the 10-year auction performance of first-edition books is the foundation for the Rare Book Index.
The 200 most valuable coins are listed and tracked on the GB200 Rare Coin 200 Index. It has produced 10 year capital growth of 194.9% and a compound annual growth rate of 11.4% for the last 10 years. During that period the most valuable coin, a Charles II Gold Guinea 1663, rose in value by 780%.
Stanley Gibbons launched the world’s first rare book index measuring the value of 30 first edition 20th Century classics. It is based on actual sale prices achieved at auctions over the last ten years and a reliable guide for investors looking to build a rare book portfolio as part of a long- term investment strategy.
