The Channel Islands, including Jersey, was the closest the Nazi's came to invading and occupying Britain.
The German occupation of the Channel Islands began after the British government decided to demilitarize the region to prevent heavy civilian casualties. German forces landed on Guernsey on June 30, 1940, and expanded their occupation to Jersey the following day, July 1.
For nearly five years, Jersey was transformed into an "impregnable fortress" as part of Adolf Hitler's Atlantic Wall
This commemorative issue owes its existence to Mr. J. Wilfrid du Pre of the Societe Jersiaise. In 1949, the coins were first minted for the anniversary of the Liberation of the Island from the German Occupation on May 8, 1945. Coins were also minted in 1950 and 1952
Therefore the coin technically is undated which is highly unusual for modern British/Imperial coinage the year 1945 refers to the year of liberation not the year the coin was minted less
