Now I know how much I'm worth: not as much as Jesus, who I'm told was sold for thirty pieces of silver. I am worth two silver coins and a haunch of goat.
-- Astri (White Bear King Valemon paragraph 28)

Importance: Astri is about to leave the home of her Aunt and she sees the two coins and the piece of meat on the table. She knows this is what Svaalberd paid for her.

-- Astri (The Drop of Tallow paragraph 5)

Importance: Astri is settling in at Svaalberd's house and she has to admit that there is enough food here, especially compared to what she had to eat at her Aunt's house. Despite the fact that her life can be better in some ways, Astri wants to be back with Greta.

-- Astri (Straw into Gold paragraph 33)
