In "The Three Brass Pennies," how does Ah Fo's decision to give back the magic pennies affect the magician?

1 Like Ah Fo, he learns that hard work and honest effort bring more happiness than power or money.

2 He insists that Ah Fo keep the pennies and helps him make sensible wishes for a castle and a wife.

3 Because of Ah Fo, the magician no longer allows people to choose what they want to wish for.

4 It teaches him that the magic pennies are dangerous to people and he keeps them for himself.​​
