How to make animation and particles for a coin?

Question

Unity

I made a beautiful animation of twisting and lifting up and down for a coin.

If there is only one coin, then everything works fine, but when I want to bet more ...

Since the animation is one and made in one place, then all the coins are teleported to this place, and do not move from their current position. How to fix it.

And if anyone knows how to make particles fly out?
The coin is destroyed when touched, and the particles attached to it, too. I can spawn particles and then destroy them, but how do I make sure that if the effect ends, then the particles are removed?

Thanks in advance!!!
