¾ Sho - Pratap Simha

Pratap Simha ruled Nepal for less than two years, dying in 1777 at roughly eighteen years of age, making his coinage issues among the shortest-reigned of any Shah monarch. The ¾ Sho denomination itself is a distinctly Nepalese fractional unit tied to the tanka-based system then in use across the Kathmandu Valley kingdoms, which had only recently been unified under Prithvi Narayan Shah — Pratap Simha's father — after the conquest of Kathmandu in 1768.

Silver supplies for these issues drew on trade with Tibet, a commercial relationship that shaped Nepalese coinage weights and finesse standards well into the nineteenth century.
