The Golden Golds are an independent team in Ibaraki Prefecture, not too far north from Tokyo. Their first season was 2005, and after the 2009 season a card set was released to celebrate their fifth anniversary, though they celebrated playing five seasons instead of playing for five years.
The set starts with the manager and coaches, followed by the catchers and infielders, and then the outfielders, as has become the standard with Japanese card team sets.
All cards have a signature parallel, and I'm sure each box contained at least one of these. Nine players are in the "GG9" autographed insert set, limited to 50 cards each. Two jersey cards, with 120 copies, and a total of 200 signed "cheki" instant photos.
