The questions raised about the Salimi coins of Jahangir of Ahamadabad mint, are of course not new and were subject to some discussion in the Numismatic Supplement (NS) I, X and XII.
G.P. Taylor in NS I (1904, p.68-73) gives an quite convincing explanation for the use of Yr. 50 and Yr.2, the succeeding solar year.
Akbar died on 2 Aban, 50th Jalus; Jahangir’s coronation took place on 10 Aban, 50th Jalus Akbarshahi (24-10-1605)
The official date of accession and Jalus starts from Nauroz, entrance of the moon into Aries, 11 Zi-l-qa’da 1014AH (11-03-1606).
The Salimi coins are known of:
Yr. 50 – Ilahi month: Aban
Yr. 50 – Ilahi month: Azar
Yr. 50 – Ilahi month: Dai
Yr. 50 – Ilahi month: Bahman
Yr. 50 – Ilahi month: Isfandarmuz
2nd solar year, Ilahi month: Farwardin (=11-03-1606; beginning of 1st Jalus)
2nd solar year, Ilahi month: Ardibihist (AH1015, starts on 19 Ardibihist)
2nd solar year, Ilahi month: Khurdad
2nd solar year, Ilahi month: Tir
(Amardad) > AH1015/Ry. Ahd. Jahangiri rupee (20% overweight)
It’s clear that up to Nauroz (new year = 1 Farwardin), it was the 50th Jalus of Akbarshahi as well as the first year of Jahangir, the next solar year was the 2nd year.
Ahmadabad was given as a personal fief to Prince Salim, the future Emperor Jahangir. This may be the reason that they adopted his princely name on the coins, until the introduction of the Jahangiri rupee (20% overweight) in AH1015/Ry.Ahd
Hereafter the coins bear the Hijri (lunar) year and the number of the regnal (solar) year – thus 1015/1, 1015/2, 1016/2, 1016/3, 1017/3, etc.
Therefore there are no coins of Ahmadabad dated AH1014/Ry.Ahd.
