Sher Shah Suri and the Rupiya

How the 16th-century ruler Sher Shah Suri introduced a standard silver coin called the rupiya, the ancestor of today's rupee, alongside major administrative reforms.

The word rupee comes from the rupiya, a silver coin introduced by Sher Shah Suri, who ruled northern India from 1540 to 1545.

The reform

Sher Shah issued a standard silver rupiya weighing around 178 grains (about 11.5 grams), along with copper coins called dams and gold coins called mohurs.

The name comes from the Sanskrit rupya, meaning shaped or stamped silver.

Why it mattered

A standard coin with reliable weight and purity made trade easier across the empire.
It replaced a confusing variety of coins.
It connected with his other reforms.

Other reforms

Land revenue assessment based on measurement.
The Grand Trunk Road from Bengal toward the northwest, with rest houses (sarais) for travellers.
An improved postal system.

Continuity

The Mughals, who returned to power after Sher Shah, kept the silver rupee as their main coin. The British East India Company and later the British Raj also used the rupee. It survives as India’s currency today, and similar names are used in Pakistan, Nepal, Sri Lanka and elsewhere.

Lasting design

A standard, trusted coin is a public good that lowers transaction costs, helping trade and tax collection.

The trader's relief

Before the reform, a trader travelling across northern India had to deal with many different coins of varying weight. With Sher Shah's standard rupiya, he could trade using one trusted coin across the empire.

Thinking the rupee was created by the British

The rupee's origin goes back to Sher Shah Suri's rupiya in the 1540s.
