As doubts continue about the durability of “fiat” money
economies, Stanley Gibbons, the firm famed in the stamp collecting business,
has rolled out a rare coin index showing prices having risen 248 per cent since
2002, an compound annual growth rate of 13.3 per cent.
The Rare Coin Index, giving a representative sample of 200
rare British coins, taken from the standard catalogue of UK coins, is
designed to capture growth in pieces ranging £225,000 to £5,000. To give one of
the strongest examples, a 1247-1272 Henry III gold penny with sceptre mark
fetched a price of £225,000 this year, a jump of 309.1 per cent over 10 years.
The best performer in the index- a 1663 Charles II gold
guinea – shows a CAGR of 27.8 per cent, Stanley Gibbons said.
The data is based on published auction realisations for the
last 10 years.
