I have a Volks Ruby coming home soon and I plan on wiping her face up because I don't like the one she came with. I know that there are face ups that are limited like Cyber Bohemian Shiwoo and if his face up was wiped he'd be a regular Shiwoo. But I'm talking about the actual limited heads being wiped. How do you feel about people wiping the faceup of a limited doll? Do you feel that the value of the doll drops because it doesn't have the orginal face up? Also, would you buy a limited doll without the orginal face up, or is the actual limited head more important?
