Do I have this in the right category?

[Revenant]

I'm been wondering lately if I have my signature set (in my sig block) in the right category. I decided to place it in "Thematic & Topical Coins." Would it be better to have the set under the "World Coins" category?

I think you can put it wherever you want. There is definitely a theme - bullion coins, but they are definitely all world coins also. There is no wrong answer here.
