Shah Jahan, Rupee, Patna,KM#222.12
« on: December 02, 2017, 04:37:32 AM »
Hi,
This is a rupee of Shah Jahan from Patna.
Ref: KM#222.12
Wt: 11.38gm,
However the dates on the coin are interesting.
On the Kalima side, the date is given (faintly at 3 o'clock) as 1037, i.e. his first year of rule. However on the other side, the reign year is 2.
I found a coin with similar date in https://www.zeno.ru/showphoto.php?photo=79486
What could be the reason for it?
Thanks,
Saikat

Regnal years and Islamic calendar years will not start on the same day, unless the ruler ascends on  the first day of the new year, which would be an extraordinary coincidence.

Peter,
Shah Jahan ascended on 4th February 1628 CE i.e 28 Jumādá al-ūlá 1037 AH (could not find the appropriate Persian month name).  That being almost the end of 5th month of 1037, it is very unlikely that Ry 2 be reached that year itself as almost half of the year be over.
The only plausible reason will be if the regnal year be counted predating his accession.
Thanks,
Saikat

Thank you, Saikat. I think that leaves as options:

- Shah Jahan started counting before his formal accession, in an attempt to de-legitimise his step-brother Khusrau
- the coin is a mule.
