Illustrated below are two copies of DPRK 1356 (Scott’s), one with the 15ch denomination (right), but the other without any indication of denomination (left). I have no recollection about how these came into my hands. If anyone has any additional information about this apparent error, I’d appreciate hearing from them.

The (North) ” Korean Stamp Catalogue 1946-2015″ lists this stamp as nr. 1394, but like the Scott catalogue there is no mention of a missing value error.
