How much is your cheer ghost dark master worth?
Less than one Australian dollar. The reason for this is because
there is no such thing as a CHEER GHOST DARK MASTER in yugioh,
unless you are looking at a counterfeit card. I think you must be
thinking about CHEER CHOST DARK MASTER. Which is still not a real
card. Try selling it on eBay for 5 AU. Maybe if you did this
someone in the world would come along and buy it. Sorry to tell you
