Watching the endless stream of opportunistic issues, largely directed at gullible collectors, coming out from North Korea year after year, it is a pleasant philatelic experience to encounter something unexpected from this source. It has, of course, occurred in the recent past with the discovery of the domestic paper varieties – the ‘yellow paper’ issues – that still have to be fully documented. Some perforation varieties in modern issues have also been noted.
Other undocumented varieties are to be found as a result of the revision of postal rates in 2002. Revision is a euphemistic description of the situation; effective August 1, 2002, the rate for a domestic letter increased by a factor of 30(!) from 10chon to 3won – pity the poor aspirant capitalist who was hoping to accumulate a few won in the bank.
