TITLE: What are some examples of coarse moduli spaces?
QUESTION [11 upvotes]: It took me some effort to work out Gerashenko's nice simple example Can a singular Deligne-Mumford stack have a smooth coarse space? of a DM stack non-equisingular with its coarse moduli space, which means I must improve my understanding of coarse moduli spaces. 
What are your favourite examples of coarse moduli spaces? One per answer, please, so we can rank them.

REPLY [4 votes]: The moduli space of semi-stable vector bundles with trivial determinant over a genus $g$ curve. If the rank is 2 then the coarse space is isomorphic to $\mathbb{P}^3$!!
