CCylinders won't work for coins becausae they have spherical ends. A CCylinder is a Pill shape.
If you have to use a coin shape (you can't get away with using thin boxes) your best solution is to use several box geometries each rotated slightly, creating a multi-pronged star (still with a cylinder mesh), or more difficult to calculate placing them around the edge with one in the centre for a 16 edge polygon
Cylinders aren't well supported in ODE.
