What Is The Most Rarest/ Expensive Kpop CD?

[chaloner]

What is the most rarest and the most expensive Kpop CD? I believe Ladies Code Kiss Kiss is extremely rare. You can't find it anywhere. If it's sold on Ebay or Amazon it's being sold over $100.

They are already a retro, I suppose. 

Unfortunately, the sad event happened with Ladies Code isn't the one and the last... One day you will try to find albums of Shinee with Kim Jong-hyun vocal and couldn't find.
