Q: How much is harry potter and deathly hallows first edition with cast signatures worth?

A: A book is a collection of lines on paper. These lines create letters. The letters make words, the words sentences and the sentences paragraphs. Put them all together and you have a story.

What I'm trying to say is that a book can not have a cast. They wouldn't be able to fit inside, and you'd probably hear them scream anytime you closed it.

So, your book, covered with so-called "cast" signatures, is completely worthless. However, it does appear completely delicious.

May I have a bite?

No, I don't recall ever having to take medication.

And there's that orange yak again.
