So I picked up a Juan Perez batting helmet from 2013 in hopes that it was the batting helmet used against Mariano Rivera. They actually had two batting helmets for sale, one being Game Used and authenticated during the last home stand and one Team Issued (the one I bought). I wasn't able to purchase the authenticated Game Used helmet so purchased the Team Issued without ever seeing the game used helmet.

Did some research and photo-matching and found out my Team Issue helmet was the one used during the last home stand and MLB authenticated the wrong helmet as used during the last home stand.

Would this worry some people? I would like to give them the benefit of the doubt as 2013 they typically only had one helmet throughout the year... but still...
