Only 4,000 of each of the five designs will be circulated after being delivered to high street banks in the next few weeks.
'Guernsey Treasury authorised the coins as part of the Westminster Collection commemorative coin program,' central services director at the States of Guernsey Lee de Carteret said.
'Other commemorative coins have been very popular in the UK, such as the Beatrix Potter and Paddington Bear ones.'
This is the first set of commemorative coins in the Bailiwick of Guernsey, and Mr de Carteret hoped it would encourage more interest in the island's currency from collectors both local and further afield.
'The feedback has been very positive already,' he said.
'Currently there are around 3.4 million 50p coins in circulation in the island so finding one of the new ones will be rare.'
Featured pantomimes are Cinderella, Dick Whittington, Snow White and the Seven Dwarfs, Aladdin and Jack and the Bean Stalk, which is this year's Christmas production by GADOC held at Beau Sejour.
For £325 a set of uncirculated coloured coins can be purchased, of which there are 2,019 sets. There are also sets of the five silver coins for £30 which can be found in circulation and are legal Bailiwick tender.
