To ensure all round pound coins are either spent or returned to the bank before 15 October 2017 when they lose their legal tender status, the government has launched a new campaign to raise awareness of the new 12-sided coin.
Between March and September next year both new and old pound coins should be accepted everywhere from corner shops to parking machines.
The new £1 coin, which resembles the old threepenny bit, has been hailed as "the most secure coin in the world".
The old coin has been a favourite of savers since it was introduced in 1983.
A £2 coin design will remember the Royal Flying Corps and its contribution to the defence of Britain's skies in the First World War using new aircraft technology.
But there have been concerns about round pounds being vulnerable to sophisticated counterfeiters.
This is the first time the one pound coin has been introduced in over thirty years. The outer ring of the coin is gold coloured whilst the inner ring is silver coloured.
The high-security features include a latent image that changes from a '£' symbol to the number "1" when the coin is seen from different angles.
They will be thinner and lighter than the round pound, but slightly larger in diameter and feature an impressive hologram £1 sign.
Chief Secretary to the Treasury David Gauke said: "March 28 should be an important date in everybody's calendar this year - as we will have a new quid on the block".
Households are being warned to spend or bank all their round pound coins before October, when they will cease to be legal tender.
But businesses in the region say they have been preparing and although it will be time consuming, will not cause a major issue.
After the introduction in March there will be a transition period when vending machines may only accept old coins.
A new design of pound coin, announced late past year, will launch in March, with the old version becoming obsolete just over six months later.
