Coins of the Indian rupee rupee, 1/4 rupee, 2 anna, 1 anna, 1/2 anna & 1 pice coins, and are referred to as the anna series or pre-decimal coinage. Under the anna series, one rupee was divided into 16 annas or 64 pice, with each anna equal to 4 pice. In 1957, India shifted to the decimal system, though for a short period of time, both decimal and non-decimal coins were in circulation. To distinguish between the two pice coins in circulation, the coins minted between 1957 and 1964 were printed with the legend “Naya Paisa” (“New Paisa”). The denominations in circulation were 1, 2,
Coins of the pound sterling of the 20p coin has also been amended to incorporate the year, which had been on the reverse of the coin since its introduction in 1982 (giving rise to an unusual issue of a mule version without any date at all). The orientation of both sides of the 50p coin has been rotated through 180 degrees, meaning the bottom of the coin is now a corner rather than a flat edge. The numerals showing the decimal value of each coin, previously present on all coins except £2 and £1, have been removed, leaving the values spelled out in words only.
