Plate errors on a basic stamps

Overprint errors
Double overprints exist on stamps of 1 din, 1.50 din, 4 din and 5,50 din. Double overprints (one blind) also exist.
Inverted overprints exist on stamps from Mi 1-6 stamps, and those inverted overprints are partially caused by the wrong orientation of the sheet for the overprints. There are also inverted overprints caused by the insertion of new stamps in damaged sheets of basic stamps, where it sometimes happened that stamps were placed inverted.
There are also shifted overprints, some of them due to accidental folding of the corner of the sheet edge when feeding it into the printing press.
