Actually it's the Interior minister, the original OP probably made a mistake.

The phone conversation goes like this:

+son, tell me what do you have at home? is there anything...

-no dad, what can I have?

+how much money do you have at home?

-only left overs from my own money, just few cents((3-5 kurush is an idiom to describe small, almost neglectable amounts of money)), you know about it...

+how much?

-about 1,000,000 Turkish liras(he says 1 trillion, in old currency - Turkey dropped 6 zeros from it's currency but people often use the old numbers) dad...

1,000,000 is about 450,000 USD

Thanks, makes a lot more sense now (especially the part about dropping 6 zeros)

The son refers to a trillion as "just a few cents". Which indicates they probably have a much higher amount of money kept secret.
