Flipping through the Moldova section of a Michel Osteuropa 2009/2010 Catalog (Band 7), I've noted that the country was established in 1991, and that the sets and souvenir sheets it has produced since then have been issued in low to moderate quantities- mostly 100,000 or fewer, with many under 30,000. Furthermore, many of Moldova's issues are attractive topicals, with international appeal.
On the other hand, Moldova is the poorest country in Europe, and about a quarter of its population of 3 1/2 million live on less than $2 per day. The country has no mineral deposits but enjoys a favorable climate and good farmland, and depends heavily on agriculture (mainly fruits, vegetables, wine, and tobacco). Currently, Moldova imports all of its supplies of oil, coal, and natural gas, mostly from Russia, and consequently is extremely vulnerable to increases in energy prices. Annual GDP growth has been strong recently, averaging about 5.5% over the last five years.
