No serial numbers on any of these mp 59 clubs. Grain flow forged on them. Got them from a reputable dealer a while ago.

The photos suck so bad I can't tell.... but I'll go with what others said. I'm pretty sure Mizuno only puts a serial # on the 6 Iron
I got them from global golf 2 months ago. Haven't touched them. Randomly came across an article about how to look for counterfeit clubs, and then saw there was no serial numbers on it. Well, I'll call them tomorrow to see. I'm hoping they will be cool, considering I've spent thousands with them.
A guy a while back was listing them as Tour issued heads. I wish I was joking
