The Catalogue of Coins in the Panjab Museum, Lahore, Volume I: Indo-Greek Coins by R.B. Whitehead is a seminal work on the numismatic history of the Indo-Greek period. Published in 1914, it is a meticulously detailed catalog documenting the collection of Indo-Greek coins housed in the Panjab Museum, Lahore. The book provides comprehensive descriptions of coin types, inscriptions, symbols, and portraits, along with historical context for each ruler represented in the collection. Whitehead's scholarship includes a systematic arrangement of coins by dynasty and ruler, making it an essential reference for historians, archaeologists, and numismatists studying the Hellenistic influence on the Indian subcontinent. It reflects the rich cultural and artistic exchange between Greek and Indian traditions during the Indo-Greek era, offering insights into political history, iconography, and economic systems of the time. R.B. Whitehead (1879-1967) (Reginald Buckingham Whitehead) was a British numismatist and historian renowned for his expertise in Indian coinage. Whitehead was a member of the Indian Civil Service and developed a keen interest in numismatics during his tenure in colonial India. His meticulous research and detailed cataloging helped preserve and document the rich numismatic heritage of the region, particularly focusing on the Mughal Empire's monetary system. His contributions remain a cornerstone for historians, collectors, and researchers studying South Asian numismatics.
