Guernsey - 20p - 1983 Reverse showing a milk jug. The original decimal series introduced by Guernsey, rather oddly, didn't feature a portrait of Queen Elizabeth II. Instead the coins issued continued to bare the same designs on the obverse as used on the last series of pre decimal coins. However all Guernsey coins from 1985 replaced the Guernsey sheild with a portrait of the Queen although the shield is still present, behind the Queen's head.
