Over the course of level 11, you should acquire the standard array of items (Level+1, Level+2, Level+3, Level+4), along with 18,000 gp in various coins/gems/consumables/art objects.
Edit: Ninjad!
Edit++: Interestingly enough, there is actually a pattern (almost) to the gp amount per level, though like with the levelling formula it is a kinda wacky one.
Over level 1, the group gets 720 gp in treasure.
From levels 2-5, the group gets 320 gp more than the previous level in treasure.
From levels 6-10, the group gets 1,600 gp more than the previous level in treasure.
From levels 11-15, the group gets 8,000 gp more than the previous level in treasure.
From levels 16-20, the group gets 40,000 gp more than the previous level in treasure.
From levels 21-25, the group gets 200,000 gp more than the previous level in treasure.
From levels 26-30, the group gets 1,000,000 gp more than the previous level in treasure.
Note that eachtime the rate of increase itself ticks up, the modifier is 5x the previous one. (Which I recall is the same formula of increase tied to the magic item value.)
The only exception to the pattern is levels 2->3->4, where level 3 falls 5gp behind the expected amount, which gets made up for at level 4. For some inexplicable reason.
Anyway, I figured I'd check and see if there was an easy enough pattern to be able to calculate treasure value for any given levels without the books. And the answer is... yes, though it is probably easier most of the times to fish out the books and look it up in them anyway.
