Value of rare British stamps increase dramatically
Gibbons indicates 14 stamps out of 30 in the Index have risen in price by 100% or more since 1998. Most notably, an unused 1903 10d dull purple & carmine official (SG O40) has seen an increase in value from £5,000 in 1998 to £20,000 in 2005 (300%), as this area of philately has undergone a rerating by collectors.
Another example, the 1882 £1 brown-lilac (SG 136) has risen from £31,000 to £70,000 (an increase of 125%) over the same period, as its scarcity – only a handful are known in investment grade condition - has become fully appreciated by philatelists.
