Each month, Games Workshop has a new exclusive figure and coin at their GW stores. Seeing as it's the start of the month, there's the new, November set, available now.
From the post:
Christmas is right around the corner, and Da Red Gobbo has been blocking out time from his busy schedule*, preparing to deliver presents to everyone at your local Warhammer store.** Yes, it’s only November, but he’s been really keen this year, and he’s a tad worried that his grot friends will try to swap these freshly minted commemorative coins for extra squig nuggets.
