I recently purchased a set of Titleist AP1 712 irons with the serial # appearing on the Titleist security label. The serial number has repeating 0's, which appears to contradict the following:
2. Unique serialized number: Each label will feature a unique serialized number that can be found under the words "Certified Authentic" which can be found in the middle of the label. This unique number will not repeat.
Are these clubs genuine since they have a repeating serial #?
