horseman were almost invariable devices on Rajput copper and bullion coins. Eastern Ganga Empire (1038–1434 CE) The Eastern Ganga coinage consisted of gold fanams. The obverse typically depicts a couchant bull along with other symbols. The reverse features a symbol which represents the letter sa (for samvat, which means year) flanked by elephant goads or an elephant goad with a battle axe, along with a number below, which depicts the regnal year(anka year) of the reigning monarch. Some coins also carry the legend śrī rāma on the reverse above the letter sa. An interesting aspect of the Eastern Ganga coin dates is that these coins may be the earliest Hindu coins using decimal numbers for dating. Earlier dated coins, such as those of the Western Satraps, the Guptas etc., used the old Brahmic numbering system with separate symbols representing each of the single digits, separate symbols representing two-digit multiples of ten, such as 20, 30, 40, and so on, and further separate symbols representing three-digit numbers such as 100, 200, etc. Thus a number like 123 was written as 100-20-3. But the Eastern Ganga coins were written using the symbols for the single digits, with the position of the number indicating the value such as tens or hundreds, thus effectively using the Zero-place holder system. Ahom Kingdom (1228–1826 CE) The earliest coins from the Ahom kingdom date from the 15th century, from the reign of Supatphaa (Gadahara Simha). The coins are of octagonal shape with Assamese legends dated from Saka era written on both sides in scripts ranging from Ahom script in early coins to Eastern Nagari on coins from 16th century. Ghaznavids Some bilingual silver jitals were issued by the Ghaznavids from Lahore included both Arabic and Sanskrit inscriptions, with Sanskrit in Sharada script. Late Medieval and Early Modern period (c. 1300–1858 CE) Delhi Sultanate (c. 1206–1526 CE) Razia Sultana Razia Sultana was one of the few queens regnant in the history of India, and thus one of the few women to issue coins. Alauddin Khalji Alauddin Khalji minted coins with the legend struck as Sikander Sani. Sikander is Old Persian for 'victor', a title popularized by Alexander. While sani is Arabic for to 'second'. The coin legend (Sikander-e -Sani) translates to 'Second Alexnder' in recognition of his military success. His coins omitted the mention of the Khalifa, replacing it with the self-laudatory title Sikander-us-sani Yamin-ul-Khilafat. Token currency of
