Ok, so I have had this full set for around 4 years. I got it at a major idoc on Atlantic or Lake Austin (don't remember). I have no clue if they are duped. I have been holding them fully expecting them to disappear. Is there a way to tell if they are duped? I have been told that it is very rare to have a full set of them. But someone would have to have a set to dupe a set right? What would a set be worth?
