when i pause a game using UI panel and freezing time, my falling coins in the level is still showing.

public void OnMouseDown() {

      {
         paused = !paused;
     }
     if (paused) {
         PauseUI.SetActive (true);
         Time.timeScale = 0;
         gameObject.active = false;
         GameObject.Find ("Button").transform.localScale = new Vector3(0, 0, 0);

         // Show button


     }
     if (!paused) {
         PauseUI.SetActive (false);
         Time.timeScale = 1;
         GameObject.Find ("Button").transform.localScale = new Vector3(1, 1, 1);
     }
 }

simple code for calling
