According to Gerhard Schön, the "Second Anniversary" commemorative sets (with a mintage of 3,000 pieces) were produced by the UGDO (Usine Genevoise de Dégrossissage d'Or) in Geneva and were made for H. William Bernhardt and his Markpress PR agency which worked for the Biafran government then. Remick (1971) says that Markpress (listed there as "the official distributor") was selling the sets for $464.
