“Lilies, I rule, heads, you do," he [the King] said, and threw the coin into the air."Lilies, you rule, heads, you throw again," said Attolia.The coin dropped. Eugenides looked at it and then showed it to her. "No need," he said. The coin sat in his palm, obverse, showing the lilies of Attolia. He flipped it again and again and again. Each time it landed showing the lilies. ...(Relius)He wanted to dismiss the coin toss as slight of hand. Any circus performer could control the drop of a coin, but he'd been puzzled. The queen had been undismayed; she had seemed almost vindicated in her manner. It had been the King who was more disturbed with each toss of the coin. He'd looked almost sick, Relius thought, by the time he put the coin away....Walking away along the arcade that lay perpendicular to the one where Relius lurked, the king pulled the coin from his pocket.

If she was not her father's daughter, who was she?"...mad," he finished. "But I see no taint in you.""Taint?" Dany bristled."I am no maester to quote history at you, Your Grace. Swords have been my life, not books. But every child knows that the Targaryens have always danced too close to madness. Your father was not the first. King Jaehaerys once told me that madness and greatness are two sides of the same coin. Every time a new Targaryen is born, he said, the gods toss a coin in the air and the world holds its to see how it will land.”
“Look at a coin from your pocket. On one side is "heads" - the symbol of the political authority which minted the coin; on the other side is "tails" - the precise specification of the amount the coin is worth as payment in exchange. One side reminds us that states underwrite currencies and the money is originally a relation between persons in society, a token perhaps. The other reveals the coin as a thing, capable of entering into definite relations with other things.”
