1 Rupee no Urdu on reverse

The "no Urdu on reverse" designation marks a printing anomaly within the P#25 series — the Urdu text normally present on the back was omitted, producing a variant distinct enough to list separately. Whether this resulted from a plate error or a deliberate short-run modification at the Karachi facility has never been definitively documented.

By 1981, the 1 Rupee note was already an anachronism in practical terms, with coins handling nearly all transactions at this denomination. The Pakistan Security Printing Corporation continued producing it regardless, as official policy kept paper notes in the mix far longer than circulation demand justified.
