Not quite a new release, but I just picked up my sample from this set a couple weeks ago.
Released in December, the latest Greatest Games set focuses on the game played between the Swallows and Tigers on October 16, 1985. This game gave the Tigers the league championship - and it ended on a tie! This was the first time the Tigers were league champions in over 20 years.
Each box comes with a complete base set of 36 cards, plus one special card. There are 3000 sets in total, and their retail price is 4000 yen.
There are four "Special Insert" foil-signed cards with 60 copies each, plus a triple foil-signed card with 34 copies. If you're wondering, Randy Bass appears on one of the 60-copy cards, plus on the triple card. I haven't seen one of these online or in stores - only 274 (less than 10%) of the sets include a foil-signed card.
