For the enlightenment of everyone what do you consider a duplicate? Unless otherwise stated I would presume that any variation of a card is a different card (I collect all variations). There are many cards with only slight variations that at a glance look like duplicates. Examples include different printers initials on the reverse, different telephone number for the casino, different colored shoes on the character on the front, etc. The last round robin I received had some "duplicates" in it but I happened to need some of those variations and was happy to get them. With 50 or 60 cards in a RR I can see how one duplicate may be put in by accident but if you are getting 5 duplicates then either someone is not following the rules or they are true variations. Knowing most of the people here as well as I do, I would like to think that they are variations.
