The British peyton manning l jersey public have already got accustomed to the new 5p and 10p coins introduced last year. There are still three coins left to come the 2p worth 4.8d, 1p (2.4d) and half pence (1.2d).
The DCB has stockpiled 120 million 50 pence coins at banks around the country ready for today's introduction of the coin, making it the largest ever issue of a new coin.
Lord Fiske said the reason for this was to replace the 200 million ten bob notes as soon as possible.
He said the issue would eventually save the Treasury money. "The note is being replaced primarily on economic grounds. A 10s note has a life of some five months and the costs of distribution and withdrawal are comparatively high.
"Although a 50p coin will cost more to produce initially, it should have a life of at least 50 years and the metal will subsequently be recoverable."
But many people were unhappy with the new addition to their purses and pockets.
