Note: This exceptional piece represents the earliest known variant of Akbar’s Ilahi-type Gold Heavy Mohur series, distinguished by the prominent numerical countermark ‘30’. This countermark reflects the earliest recorded date reference in Akbar’s Ilahi era, a system that would soon become a hallmark of his imperial coinage.

The Ilahi calendar was instituted by Akbar in AH 992 (1584 AD), retrospectively calculated from his accession year, AH 963 (1556 AD). The countermarked date, Ilahi year ‘30’, thus corresponds to the formal launch of this unique calendrical system. The Ilahi year commenced with the Vernal Equinox, aligning with Nowruz, the Persian New Year, and followed a solar structure of twelve Persian months, designed by the polymath Fathullah Shirazi, a leading figure at Akbar’s court.

Initially, coins struck under the new system were issued without date inscriptions. Recognizing this oversight, the administration retrospectively applied counter-stamps bearing the date ‘30’ to previously issued mohurs. This coin is an exceedingly rare surviving example of that early corrective phase, offering a direct link to the experimental origins of Akbar’s innovative coinage and calendar reform.
