Hmmm, it's actually 4. It seems like 6 stacks in my game since 2 piles of broad skulls and 2 of jawless skulls don't stack.
Guess it's not as bad as it seemed then (provided those 2 similar stacks of the same item aren't actual different items aswell).
The other 2 being skull and ancient skull (the only one being different, albeit only because of base price).
