I don't know much about the spice trade, but I can give you a bit of problems you'll find talking about the "gold" extracted from the Americas. Firstly, quantitatively, you might get records of gold sent during the beginnings of colonialism. But what really made the Spanish crown rich was silver, the famous Spanish Dollar. That's what we're talking about here, rather than gold, that's where the economic value was in the Americas.

Unfortunately, what this is "worth" is pretty problematic; it caused extreme inflation. The Ottoman Empire's economy was hit really badly because they had been one of the largest producers. In Spain it got the point where they bled the market dry; for a time, new world acquisitions stopped being particularly profitable because they were producing stuff in such quantity it wasn't valuable any more.
