Annual number of coins released into general circulation (excludes proof sets) A decimal quarter-penny coin (to be struck in aluminium) was also proposed (which would have allowed the pre-decimal threepence to continue to circulate with a value of new pence), but was never produced. Halfpenny (British decimal coin) The British decimal halfpenny (p) coin was introduced in February 1971, at the time of decimalisation, and was worth one two-hundredth of a pound sterling.

Decimal and ["x"] amounts to which is either 0, if "d" = 0, or gets arbitrarily small, when "n" tends to infinity. According to the definition of a limit, "x" is the limit of ["x"] when "n" tends to infinity. This is written as formula_7 or which is called an infinite decimal expansion of "x". Conversely, for any integer ["x"] and any sequence of digits formula_8 the (infinite) expression is an "infinite decimal expansion" of a real number "x". This expansion is unique if neither all "d" are equal to 9 nor all "d" are equal to 0 for "n" large
