Rajgor, D. Punch-Marked Coins of Early Historic India. (Mumbai, 2001).
The monograph chronicles 200 years of numismatic history of the Indian Subcontinent. The period covered in book the ranges from the rise of Janapadas (States) in c. 600 BC to the rise of the Shishunagas in c. 400 BC. In writing the monograph, the author has studied 10,000 punch-marked coins and 66 coin-hoards. Based on this study, he has forwarded a Catalogue of Coins of 1,288 coin varieties in electrum, silver and copper. All these coins are classified into 83 Coin Series assignable to 17 Janapadas like Kashi, Kosala, Panchala, Shurasena, Magadha, Surashtra, Avanti, Ashmaka, Shakya and Gandhara. This attribution is a synthesis of two important factors, provenance of coins and location of ancient Janapadas during the early historic period. Consequently, the volume is classified into 12 parts, consisting 21 chapters comprising of location of Janapadas, their historical outline and coin hoards known from that region. Moreover, Catalogue of Coins lists every variety of punch-marked coins assignable to respective Janapadas. Furthermore, two appendices enlist modern forgeries and an Index of Main Symbols.
