When the militant monks sent by the Duke of Normandy came to Guernsey around 960, they brought the very best of French cattle. Over the centuries, they developed the Guernsey breed, which is known for its high-quality milk. The Guernsey Cow consumes 20-30% less food per gallon of milk compared to other larger breeds.
This coin was issued for circulation in 1956 (KM17), and again in 1959 on a thick flan (KM18). This example is one of the (very) thick coins, and was issued in 1966 for collectors.
