Here is an NGC encapsulated penny, supposedly XF-45, featuring an often maligned John Lackland, the Prince John in the Robinhood story, and King John to the rest of the world after he assumed the crown following the death of his more famous brother. King John got into dispute with his nobles, and they rebelled. He created an army called "John's Army" to face off against his nobility, and they came at him with an army named "Army of God". In a rather predictable outcome, the Army of God defeated John's Army, and he was forced to sign the Magna Carta. But poor John's troubles with his nobles continued, and he ended up fleeing for his life, lost the ancient crown jewels of the King of England, and was so depressed by this loss that he soon fell ill and died of dysentery.
