This type of coin is very similar to that of the last right but a flag or pennant has appeared on the stern-castle of the ship. This signifies that the piece was struck in the Calais mint, then, and for 180 years to come, an English possession. There are three other points of interest in the Nobles of this period. First some of the early pieces of the reign were struck from the dies of the previous king, Edward III. Secondly, a symbol, such as a lion, trefoil or crescent was sometimes placed on the ship's rudder. Fours such marks were used, their purpose being to distinguish different issues. Finally, four styles of lettering were used.
