1 Tangka 'Ga-den Tangka'

The Ga-den Tangka was struck over roughly nine decades with deliberate conservatism — the Ganden Phodrang government made no attempt to date individual issues, which makes precise attribution within the series nearly impossible without die study. Production was handled by hand-hammering techniques long after machine minting had become standard elsewhere in Asia, a conscious choice that kept the coins irregular in shape and thickness throughout the entire run.

Tibet's monetary isolation was partly strategic. The 1793 Sino-Tibetan agreement following the Gurkha invasions gave the Qing a role in Tibetan coinage, but the Ganden Phodrang steadily reasserted autonomous minting through issues like this one.
