@MonteJCook, can you answer this question brought up by @RichBurlew's OOTS? What is the preferred currency of the Elemental Plane of Earth?

@mikemearls and @ChrisPerkinsDnD too: What would you use in a metal-rich environment like the Elemental Plane of Earth instead of gold?

@mepstein73 gold's value = rarity plus ease of working. I'd opt for something odd, like ice or wood, that's rare in that environment
