Decimal Day three of the six new coins. Small booklets were made available containing some or all of the new denominations. The old halfpenny was withdrawn from circulation on 31 July 1969, and the half-crown (2s 6d) followed on 31 December to ease the transition.

There was a substantial publicity campaign in the weeks before Decimalisation Day, including a song by Max Bygraves called "Decimalisation". The BBC broadcast a series of five-minute programmes, "Decimal Five", to which The Scaffold contributed some specially written tunes. ITV
Decimal enough (for all "n" greater than some natural number "N"). If all "d" for "n" > "N" equal to 9 and the limit of the sequence formula_9 is the decimal fraction obtained by replacing the last digit that is not a 9, i.e.: "d", by "d" + 1, and replacing all subsequent 9s by 0s (see 0.999...). Any such decimal fraction, i.e., "d" = 0 for "n" > "N", may be converted to its equivalent infinite decimal expansion by replacing "d" by "d" − 1, and replacing all subsequent 0s by 9s (see 0.999...). In summary, every real number that
