I actually don't know. The reciept didn't list the books individually, but I do know that the two hardback books were $7 each, so $14 dollars for those, and my total was $19 and some change, so I'm guessing Casino and The Godfather were probably around $2.50 each.

*Edit*

I found another reciept in the bag.. $0.75 for The Godfather.
