ll the finds, as will be seen, were of silver coins. Find No. 
11 was excellent in point of preservation and contained a Kam 
Bukhsh rupee of Bijapir 1119 ahd. In find No. 9 was a Bija-

of Muhammad, Ahmad and ‘Alamgir IJ. The last is believed 
to be anew mint forthis Emperor. There was also a Sironj rupee 
of ‘Alamgir II in this find. On the whole the year has been 
rather disappointing. Three of the finds of Mughal coins wete 
in very poor condition, being badly defaced by shroff marks. 
It would be a great help if the Nagpur and other museums 
would send lists of their collections and their acquirements.
