This series bridges one of the most turbulent reorganizations in Pakistani monetary history — issued in the years immediately following the 1971 secession of East Pakistan and the formal creation of Bangladesh, when the State Bank was managing a drastically reduced economic territory and a shattered public confidence in state institutions. Ghulam Ishaq Khan, whose signature appears in two prefix variants here, was serving as Finance Secretary before his long ascent to the presidency.

The fractional serial prefix variants signal a mid-run change in numbering methodology, not a separate issue — a bookkeeping shift that collectors sometimes misread as a distinct type.
