"Urdu-i Zafar Qarin" literally means "Camp associated / closely linked with Victory" so predisposes a battle and it's victorious outcome. The earliest use on coins is found in context with Akbar's Mewar campaign. However, the silver and copper coins with date "Alf" were struck in AH990 when Akbar celebrated the Islamic "Millennium", making the "Victory" referred to as entering a new "era" in which he was going to be the Messiah or a Khalifa. The coins might have been struck at many mints, but the dies appear to be centrally manufactured, perhaps at Fatehpur, and distributed to principle mints across the empire.
