i bought two decks of monarchs the other day and saw that the borders had different widths (this makes the deck one way) Is it suppose to be like this (Both the decks and all the cards have the problem)
I don't own any decks of Monarchs, but I have standard Bicycle cards that have different border widths. I think it's just a product of the mass printing process that the United States Playing Card Company uses.
I have a deck of monarchs and would not call them one way backed, due to all decks printed by the USPCC have this. Its not unusual or anything to worry about. Like purplemustache said its just a slight error when they're in the process of printing, its no biggy
