Check the goblin in Idyllshire next to the person who upgraded combat gear. You'll need Goblin Dice or Goblin Cups, I forget which, as the hand in along with the i180 to upgrade it to i200. The Goblin stuff is bought with either red scrip or red tokens, not sure since 4.0 as I've not looked.

That said, 650 GP worked wonders in HW. 700 GP worked wonders for me leveling in SB, because the 15% gathering move that cost 100 GP was very useful and affordable, while still maintaining the 600 GP Collectible rotation.
