For many years we have been searching for a world wide expert who can expertize the entire non US world. For the US area there is the Philatelic Foundation but they really don't do much with Foreign stamps. We wanted an expert who expertized a large number of countries and areas, who didn't indelibly mark the stamps whether they were genuine or not (which eliminated the German Bundesprufers who handstamp everything), who had a fast turn around time and, most of all, was accurate with clear lucid certificates that are sometimes as nice as the stamps themselves. The expert's name is Sergio Sismondo. and his address is 10035 Carousel Dr, Syracuse, New York 13290, telephone 315-422-2331. And his wife Liane is one of the nicest and professional people in the stamp business to deal with. And did I mention that their certificate costs are usually much cheaper than their competitors. Take a look at their website http://www.sismondostamps.com/.
