  Let $f,g: X\to G/K$ be maps from a closed connected orientable manifold $X$
to an orientable coset space $M=G/K$ where $G$ is a compact connected Lie
group, $K$ a closed subgroup and $\dim X=\dim M$. In this paper, we show that
if $L(f,g)=0$ then $N(f,g)=0$; if $L(f,g)\ne 0$ then $N(f,g)=R(f,g)$ where
$L(f,g), N(f,g)$, and $R(f,g)$ denote the Lefschetz, Nielsen, and Reidemeister
coincidence numbers of $f$ and $g$, respectively. When $\dim X> \dim M$, we
give conditions under which $N(f,g)=0$ implies $f$ and $g$ are deformable to be
coincidence free.
