sorry to hear about your friend... i had a passing interest in stamps when I was younger... looked at your friend's collection, nothing special, as most of the stamps are from the 1980s... the only exception MAY be the Malaysian stamp with the Kanji characters on it, which states "Japan Post, 6 cts", this would most likely have been from the 1940s, when Malaysia was under Japanese occupation, that one may be worth something.
