I continue to view Soccer topical issues as the most compelling investments among Sports topical stamps. Soccer is the most popular sport in the world, with a following of billions of fanatical fans, many of whom live in emerging market nations. Philatelic investors who focus on better Soccer topicals will certainly get more out of it than a kick in the shins.
A small nation of 4 1/2 million people, Costa Rica is unique as the only Latin American country to have escaped the plague of repressive dictatorships and oligarchies endemic to the region. Costa Rica has generally enjoyed greater peace and more consistent political stability than many of its fellow Latin American nations. The government offers generous tax exemptions to those investing in the country,and in recent times electronics, pharmaceuticals, financial outsourcing, software development, and ecotourism have become the prime industries in Costa Rica's economy. High levels of education among its residents make the country an attractive investing location. Annual GDP growth has averaged 5.6% over the last 5 years.
"The Stamp Specialist" blog features my buy prices for stamps which I am interested in purchasing. I've posted a buy list for Costa Rica, including the set recommended in this article. Viewing dealers' buy lists every now and then is an excellent way to keep current on the vagaries of the stamp market.
