This is a super rare Jack Skellington 16" Scale Figure Collectible Doll in Original Dark Green Coffin from JUN Planning Company, No. N-009. This is one of the rarest face variation editions.  I purchased this at the Wizard World Chicago Comic Con in 1998 or 1999 and has been stored in my collection ever since.  

Jack is in perfect shape with two interchangeable heads (Open Mouth, Worry). The coffin has some scuff marks from storage.  Please see pictures for details.
