How do I Make A Sprite Act Like A Particle?

Hello and thanks for looking.

I want coins to burst/explode from an object in the way particles would. Im having trouble. If I assign random(0,360) to the instantiated coin's angle it gives me a random angle every tick as opposed to just a single random number.

Any thoughts on getting the coin(s) to act like a particle?

Thanks

coins on created

set angle of movement to random()

Thanks LittleStain, that was driving me crazy.
