I apologize if this is the wrong place to post this. I've come into possession of a blank Unhinged filler card (normal Magic back, silver border with blank center front). I can find plenty of black-bordered filler cards on eBay, but I have no idea what this one is worth. Has anyone seen one of these sell before, and for how much? Thanks!
