Game object position issue in unity3d

Question

I have a set of objects placed on the same layer where all the objects are invisible except one. When I drag an object into a selected area, the current dragged object gets destroyed, and the object should be loaded in the same position. I have added polygon collider and rigid body (SET FIXED ANGLE) to all the objects. The problem here is: when I drag the object to the selected area, the object gets destroyed, and the next object gets loaded, but the position varies when the object is loaded.

public Vector3 ObjectSpawnPosition1;
public GameObject obj1;
void OnCollisionEnter2D(Collision2D col) {
  if (col.gameObject.name == "SemiCircle") {

    if (Input.GetMouseButtonUp(0)) {
      scoreCalculate.currentScore += 10;
      Destroy(gameObject);
      Instantiate(obj1, ObjectSpawnPosition1, Quaternion.identity);
      obj1.renderer.enabled = true;
    }

  }
}

Try assigning the position of the previous GameObject to the spot where you want the new one instantiated before destroying the old object.

public Vector3 objectSpawnPosition1;
public GameObject obj1;
void OnCollisionEnter2D(Collision2D col) {
if (col.gameObject.name == "SemICircle" )
{ 

        if(Input.GetMouseButtonUp(0))
        {
            scoreCalculate.currentScore+=10 ;
            objectSpawnPosition1 = gameObject.transform.position;
            Destroy(gameObject);
            Instantiate(obj1, objectSpawnPosition1, Quaternion.identity);
            obj1.renderer.enabled = true;
         }  

}
