Nope...I didn't...I don't see this variety listed in my 2003 Red Book either....might be a rare find....I'll like to see the pics.
Welcome to the Forum! I have not heard or seen one and lincolncentresource.com does not list any 1996 Double Dies. When you can post a pic someone here might be able to help you to determine if it is a Double die or mechanial doubling. Until you can post a picture, where is the doubling on your coin at?
