Overview

The Pustaka Dharma (Pana in Sanskrit sources) was the primary coin and accounting unit of ancient India from the Mauryan Empire through medieval periods, representing one of the world's longest continuously-used coinage traditions. The pana existed in multiple physical forms and compositions depending on kingdom and period, establishing it as the flexible foundation of Indian monetary systems. The pana system represented Indian monetary sophistication and the adaptation of coinage to diverse regional and temporal circumstances. Sanskrit economic texts (Arthashastra) document the pana as the standard unit of Indian commerce, military pay, and taxation. The pana's persistence for 1,500+ years demonstrates the remarkable stability of Indian monetary traditions and their fundamental importance to Indian commerce.

Historical Origins and Etymology

The pana (पण in Sanskrit) originated as the standard monetary unit in ancient Indian kingdoms around 300 BCE, particularly under the Mauryan Empire. The pana represented the theoretical unit of Indian commerce and was subdivided into smaller units (kakinī, 1/20 pana) for smaller transactions. The pana's name and concept persisted through multiple dynasties and regional variations, demonstrating its fundamental importance to Indian commerce. Ancient Indian texts (Arthashastra) extensively document the pana system and provide detailed descriptions of monetary standards, weights, and taxation calculations in panas. The pana system represented Indian achievement in establishing comprehensive monetary systems supporting commerce across the diverse Indian subcontinent.
