From 1902-05, the British issued a set of twelve stamps portraying King Edward VII for their colony of Gambia (Scott #28-39). 6,000 sets were issued, and Scott '12 prices the unused set at $227.00 .
I view this set as a conservative investment, based upon the the growth of interest in stamps of the British Commonwealth. Also, it's inexpensive and scarce enough that it's value would receive an additional boost should a significant stamp market develop in Gambia.
A nation of 1.7 million people, Gambia has a liberal, market-based economy characterized by traditional subsistence agriculture, a re-export trade built up around its ocean port, low import duties, minimal administrative procedures, a fluctuating exchange rate with no exchange controls, and a significant tourism industry. Annual GDP growth has averaged about 6% over the last 5 years.
