How to instantiate Particle System at the same place where we click a gameobject?

I want to instantiate the particle system when clicking the coins in my game but the Particle System is not appearing at the same place where my coins are.

I used this code, I don't know where to specify the position of a Particle System in the same place where I am clicking (mouse position) or where the coins are. I used prefab for my coins and tagged them. and also pickupeffect clone is created when I click the coin so I need to destroy them after few seconds

void Update ()
{
    if (Input.GetMouseButtonDown (0)) {
        RaycastHit2D hit = Physics2D.Raycast (Camera.main.ScreenToWorldPoint 
        (Input.mousePosition), Vector2.zero);
    }
    if (hit.collider != null) {
       if (hit.collider.tag == "coin") {
           Instantiate (Resources.Load ("Pickupeffect"));
           Destroy (hit.collider.gameObject);
       }
    }
}

Hope it can help you

    private Gameobject ObjectThatYouNeedToDestroy;// gameobject initialization

   void Update () {
    if (Input.GetMouseButtonDown (0)) {
        RaycastHit2D hit = Physics2D.Raycast (Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector2.zero);
    }
    if (hit.collider != null)

So, when the clicked object is a coin, then :

    if (hit.collider.tag == "coin") {

Instantiate the object at the position of object that is being hit by cursor (hit.transform.position) with default prefab rotation (Quaternion.identity).

        Instantiate (Resources.Load ("Pickupeffect"), hit.transform.position, Quaternion.identity);//instantiate particle prefab in coin position with original prefab rotation
        float DelayTime = 5f;// change delay with any value

Assign the hit object to variable ObjectThatYouNeedToDestroy, in case that the value hit.transform.gameobject can't be assessed in another function.

        ObjectThatYouNeedToDestroy= hit.transform.gameobject;// assign coin that clicked as ObjectThatYouNeedToDestroy

The last step is to execute DelayedDestroy function after delay time expires.

        Invoke ("DelayedDestroy", DelayTime);//execute function with delay
    }
}

this is the function that destroy gameobject named ObjectThatYouNeedToDestroy (coin)

void DelayedDestroy(){
    Destroy (ObjectThatYouNeedToDestroy);
}

You can get the hit.collider.gameObject position and instantiate your system in the same position after you destroy the coin. Have in mind that if the coin inherits a position different than x=0, y=0 you may want to instantiate the object and set the same parent. The code should like this:

if (hit.collider.tag == "coin") {
    ReplaceCoinWithSys(hit.collider.gameObject, Resources.Load ("Pickupeffect"))
}

and the method should be like this:

private void ReplaceCoinWithSys(GameObject coin, GameObject system){   
    Instantiate(system,new Vector2 (coin.transform.position.x, coin.transform.position.y), Quaternion.identity);
    Destroy (coin);
}

I hope this helps, hit me up when you complete your game I want to try it out :)
