Coin Particles keeps floating/moving instead of stoping after hitting ground

I’m trying to drop coin using particle emitter, but the coin just does not come to rest, instead it keeps floating/rotating weirdly.
coin_drop.blend (1.1 MB)
This problem occured after enabling Dynamic rotation. If I turn it off it just drops and stays in ground with the same rotation which it was emitted which I do not want.

I could use Rigid body but the scene I’m working on requires a lot of Coins and I need to adjust its Coin amount and timing of how and when it should drop. I need to keep adjusting each coin if I use rigid body.

If you know anything about it or workaround to get similar result, I would appreciate your help.
Thank you
