Muḥammad bin Tug̱ẖlaq’s gold and silver issues, like those of his predecessors, are identical in type. One of the earliest and most curious of these was struck both at Dehlī and Daulatābād (Deogīr), his southern capital, in memory of his father. It bears the superscription of G̱ẖ̱iyāṣu-d-dīn accompanied by the additional title, strange considering the circumstances of his death, _Al Shahīd_, “The Martyr.” His staunch orthodoxy is reflected on nearly all his coins, not only in the reappearance of the Kalima, but in the assumption by the monarch of such titles as “_The warrior in the cause of God_” and “_The truster in the support of the Compassionate_,” while the names of the four orthodox Khalifs, Abūbakr, ’Umr, ’Us̤mān and ’Alī now appear for the first time on the coinage of India. The early gold and silver, of which about half-a-dozen different types exist, were minted at Dehlī, Lakhnautī, Satgāon, Sult̤ānpūr (Warangal), Dāru-l-islām, Tug̱ẖlaqpūr (Tirhut), Daulatābād, and Mulk-i-Tilang. In A.H. 741 (1340) Muḥammad sent an emissary to the Abbassid Khalif at Cairo for a diploma of investiture, and in the meantime substituted the name of the Khalif Al Mustakfī Billah for his own on the coinage; on the return of the emissary, however, it was discovered that that Khalif had actually died in A.H. 740, so during the latter years of the reign the name of his successor, Al Ḥākim, appeared in its place (Pl. VIII, 8). At least twenty-five varieties of Muḥammad bin Tug̱ẖlaq’s billon coinage are known. From inscriptions on the Forced Currency, which included tokens representing these billon pieces, we learn the names of their various denominations. There appear to have been two scales of division, one for use at Dehlī, and the other for Daulatābād and the south. In the former the silver tankah was divided into forty-eight, and in the latter into fifty _jaitils_. At Dehlī were current 2-, 6-, 8-, 12- and 16-_gānī_ pieces, equal respectively to ¹/₂₄, ⅛th, ⅙th, ¼th and ⅓rd of a tankah. At Daulatābād there were halves (25 _gānī_) and fifths (10 _gānī_). The assignation of their respective values to the actual coins is, however, still a matter of difficulty.[54] [54] I am indebted to Colonel H. R. Nevill and Mr. H. N. Wright for this information.
