How to add a Collectable Coin to spawn above every platform created for an Infinite Runner Game

I am wondering if you can help me with this:

I have made an animation of a coin spinning around, I want to add it to my Infinite Runner Game that has random block sizes the player jumps on to keep running infinitely.

I just want the coin to spawn above/in the air of every block/jump pad that has been created and for the coin to give more points for collecting the coin/s.

let me know if you would like to see some of the coding or anything else,

here is what the game looks like as well as some of the coding:

You create the platform at 0,0 so create the coin directly after at X=0, Y= however high you want it from the block. Also give the coin the bullet behaviour so it moves left like the platforms.
