Pie (monetary subunit)

Shell currency had been used before coins became widespread, during the mid-nineteenth century, one pie was equivalent to about 12 cowry.^[3] The pie had been minted at Alipur, Calcutta but minting of the pie ended in 1942 the year before the Mint was shifted to Lahore,^[4] though it remained in circulation for a further five years. The pie was demonetized in 1947 as it had become practically worthless due to inflation during WW2.^{[note 1]}

Pakistan, however, resumed minting the pie from 1951–1957, coins from 1951 were stuck in the name of King George VI, coins produced between 1952 and 1955 were struck in the name of Queen Elizabeth II while coins from 1956 and 1957 were struck in the name of the Islamic Republic of Pakistan.^[5][6] Pakistan's resumption of the pie was in part because the Pakistani rupee was valued higher than the Indian rupee from 1949 onwards, when India devalued its currency to maintain the exchange rate with the Pound Sterling. The pie was noted in official documents and legalisation during this time - for instance the Finance Act of 1957 notes the excise for motor spirit (i.e. petrol) being "One rupee, eight annas and nine pies Per Imperial gallon" - this was to be the rate until March 1958.^[7]

Postage

In 1854 postage stamps were introduced to British India, for a letter weighing 1⁄6 of a tola or less the cost was 6 pies,^[8] In 1866 postal rates were reduced (although not the minimum cost) so a letter weighing 1⁄4 or a tola or less cost 6 pies.^[9] In 1869 a letter weighing 1⁄2 or a tola or less cost 6 pies.^[10] Equivalent stamps were used in Princely States.^[11]

Under the old currency system, each subunit of the Rupee was separated with a slash, the first number is the number of rupees, the second is the number of annas (1⁄16), the third is the number of pices (1⁄64), and the fourth is the number of pies (1⁄192). The table below shows four examples of currency notation and their decimal value:
