In the current beta build there are a few ways of obtaining these:
- Apexis Crystals: 100
- Garrison Resources: 300
- Honor: 500
- Gold: 500g
Now this is quite an interesting change. Obviously they're still tweaking the numbers, but a large sum of gold at the end of a daily dungeon could create inflation in ways we haven't seen before, but if it's balanced correctly, and people use it to buy tokens (or even gear!), it would be offset. At the time of this post, Watcher has added another comment that I find interesting:
But when it comes to heirlooms, old legacy gear, elements of garrison progression, or something like the Seal of Tempered Fate turn-in that was the original topic of the thread, gold can work just fine as a universal currency. We want to offer more ways of earning gold that don't rely on repetitive activities (killing fast-respawning mobs in a field somewhere) or playing the Auction House, so that a gold cost like the weekly Seal turn-in feels fair and accessible to the average player through the natural course of play.

Kind of interesting, but again depending on the pricing, this could turn into more of a gold sink than a source of inflation. If people now have to spend a reasonable amount of gold to purchase heirlooms (which I love by the way), if priced right, it can take a lot more gold out of the market than is put in by this daily dungeon reward.
On the second part, namely "We want to offer more ways of earning gold that don't rely on repetitive activities (killing fast-respawning mobs in a field somewhere) or playing the Auction House, so that a gold cost like the weekly Seal turn-in feels fair and accessible to the average player", I must say it seems like Blizzard is once again looking at the gold maker in a negative light. It's not a comment damning gold making in any way, but suggesting that their demographic has no interest in it, which from a statistical standpoint is probably true. This quote also verifies my hopes that these gold rewards from dungeons will mostly be able to cover the cost of seal turn ins, and not much more.
All in all, quite an interesting development, and I think it's great that we will have something other than the occasional ridiculously overpriced mount, BMAH item, etc. to spend our gold on. I've got 4 million right now just waiting to be spent, and I'd love to do it to make elements of the game less grindy, and take part in the activities I enjoy. I really like this model, I just hope that Blizzard does it right.
If you're interested in discussing this further, there's a discussion thread about this topic going on in The Consortium.
