Chen pretty much only played for the ni-gun Dragons from 2004 to 2007, only making appearances with the big club in 2005. He finally made the ichi-gun squad to stay in 2008, so he really only has four years of experience at the top level of NBP.
Due to his odd career path, he's got an odd set of baseball cards. His first card is #D34 from the 2004 BBM Dragons set. His first appearance in BBM's main set was card #295 in the 2009 1st Version set. He does not appear in any BBM All Star sets, but he is in both the 2010 and 2011 Nippon Series sets. I think his first Calbee card was #078 in the 2009 set.
Looking up his cards in SportsCardForum is kind of problematic as BBM has referred to him as "Wei-Yin Chen", "Wei Yin Chen" and even "Weiyin Chen", so you need to either do multiple searches to find all his cards or search for "Chen" and pick out the relevant cards (some of which are listed as "Wei Ying Chen").
