How to animate a 10-frame coin?

I have a coin that has a 10-frame animation, but so far the only item as coins go in my scene, is the stationary coin. I think I have to use an animator controller, but I’m not sure as how to go about doing this. Any suggestions? Thanks!

Well its a 3d coin, but when I create a new animation, I don’t see the create new clip or whatever.
