What is a 1983 £1 coin worth?

Penny Brooks

20th March 2017

For a different take on how inflation erodes the value of money, calculating 'real' values for nominal values, and considering different forms of investment, this short article on the BBC website is useful. It looks at what an investor could have done with a brand new £1 coin, when it was introduced in 1983, and what the real value of each of them would be now. Asset managers M&G have calculated the returns based on a range of alternative investment options, from 'do nothing' to fully managed investment in the stock exchange, up to the end of 2016.

The calculations in M&G's report

After taking into account the effects of inflation – which averaged 3.5% between 1983 and 2016 – the M&G report calculates that a newly minted £1 coin kept on the shelf since 1983 would be worth only 32p at the end of this period, in 1983 terms. To have retained its purchasing power, by rising in line with inflation, this £1 would have had to grow to £3.10 by the end of 2016.

Note, though, that for both UK Government bonds, and for investment in the stock exchange, all income and dividends are being reinvested rather than taken as cash. This underlines a point made by M&G's investment director, who concedes that in order to make the greatest return on the investment, it is necessary not only to accept a greater element of risk but also to make a long-term investment with no need of easy, quick access to the cash. The investment listed that seems to buck this trend, at least in terms of risk, is the high return on Government bonds, which might suggest that for a risk-averse investor, they would have been the optimal investment 33 years ago.
