I continue to like the better U.N. and U.N.-related stamps long-term. The market for these stamps should grow over the very long haul as institutions of world government develop in order to take on serious (and possibly existential) problems which can only be coped with globally. Despite the present inadequacy, corruption, and ineffectiveness of the U.N., I view its reform and gradual strengthening as a gradual but irresistible trend.
In my opinion, the best philatelic investment bets on increasing interest in the U.N. are not to be found among the regular issues of its main offices in New York, Geneva, and Vienna, but rather among peripheral items, such as the Swiss International Organizations stamps, stamps issued by UNTEA and UNIAK, and some of the scarcer U.N.-related topicals issued by various countries. The printing quantities of stamps issued by the main U.N. offices are simply too high, and I expect that much of them will be available for less than face value for some time to come.
