Undercoin? Can we get an explanation?

There seems to be a lot of confusion as to how these are obtained. Can it be explained a little more thoroughly by one of the forum-lurking employees?

My wife and I are planning to dig into some delves this evening, and I’m trying to find information about how frequent they’re dropped and if there are any specific sources, but all I can find is more confusion.

It seems that there’s an affix that makes mobs drop more of them, but mobs don’t actually seem to drop them, even with the affix. The only surefire way to seemingly obtain any is through a world quest.

Is this intended? A bug? I’d love some official clarification. At the moment it seems like most people just aren’t getting any.

I have not had time to test, but based on what I’ve been reading, it sounds like they only drop from Bountiful Delves. I’d say to try a Bountiful Delve yourself if you have a moment and see if the coins drop there.

I pulled quite a few out of bountiful delves last night, I can’t recall having gotten them on regular or not.
