pleas help me... if you can

You can have the coin instantiate another coin in a random range of positions on contact with your player

+1 to @frizuo’s approach. You could place several empty gameobjects/nodes as “spawn points” and randomly pick one for the new coin’s position.

you could do this if you want

Vector2 newCoinPosition = new Vector2(Mathf.Random(-100,100),Mathf.Random(-100,100));

Instantiate(Coin, newCoinPosition, Quaternion.Identity);

hope it helps!
