Question for those html5 canvas pros

Question

how can i make this circle to spin on its x-axis (like a spining coin on a flat surface)
which can also be useful animating pick-up coins /tools/weapons in game...i tried hard to animating it that way..but only errors...anything useful like a link to a canvas tuitorial concerning this will also be apreciated

(P.S css animations are obvious)
