Both Bats are dated 7/27/2007 on end of knob. Make sure all Marucci Bat have a date on the end of knob. If they do not have a date, they are probably just a cheaper version made to give away or just for autographs. Albert Pujols started swinging Marucci bats in 2007, one of the models he used was the CB15B, Carlos Beltran's model.
PSA stated on one of their Authentifications for a CB15B that they contacted Marucci Bat Company on the similar Bat and Marucci stated "These Bats are as authentic as it gets this was a small order that Albert placed at the beginning of our relationship with him in 2007. Albert started using the David Wright Model DW5 and A Carlos Beltran CB15 after they traded Bats before BP one day. He used them in a game, hit a few Home Runs and the rest is History. Since then we have gone on to create a model for Albert the AP5. But those are for sure Gamers and monumental for our Company." The bats were purchased from two different sellers in December 2008.
