Mistakes happen.

This time, Topps is pointing out a couple of printing mistakes on 2013 Topps Tribute World Baseball Classic Edition, which arrives in hobby shops on Friday.

The first is on the packaging, which says there is one autograph or Relic numbered to 99 or fewer copies per pack. The autographed cards are not numbered — just patch cards — in the hit-per-pack product.

Secondly, seven players in the product have different card numbers on two cards as well as the parallels — but they have the same photographs.

They are:

 Jose Berrios: WTA-JB and WTA-JB2

Jason Grilli: WTA-JG and WTA-JG2

Kelvin Herrera: WTA-KH and WTA-KH2

Luis Mendoza: WTA-LM and WTA-LM2

Miguel Montero: WTA-MM and WTA-MM2

Salvador Perez: WTA-SP2 and WTA-SP3

Carlos Santana: WTA-CS and WTA-CS2
