Loading and Saving High Score

I have been working on this for hours, watched numerous tutorials, and searched unity answers, but cannot figure out what I’m doing wrong. I want to save my highscore using player prefs, but when I refresh the game the high score is back to 0. I am using two scripts:

Code#1:

using UnityEngine;
using System.Collections;
using UnityEngine .UI;
using UnityEngine .SceneManagement ;

public class GAMEOVERManager : MonoBehaviour {

	public Text highScoreText;
	public Text scoreText;
	public Text goldTeethText;

	// Use this for initialization
	void Start () {

		highScoreText.text = PlayerPrefs.GetInt ("High Score").ToString ();
		scoreText.text =PlayerPrefs.GetInt ("Score").ToString() ;
		goldTeethText.text = PlayerPrefs.GetFloat ("Tooth Score").ToString ();
		PlayerPrefs.Save ();

	}
	
	// Update is called once per frame
	void Update () {
	

	}

	public void RestartGame(){
		SceneManager.LoadScene ("Gameplay");
	}


}

Code#2:

using UnityEngine;
using System.Collections;
using UnityEngine .UI;
using UnityEngine .SceneManagement ;

public class ScoreManager : MonoBehaviour {

	public static int highScoreCount;

	public static int scoreCount;

	public static int TKOCount;

	public static float toothCount;

	public Text TKOText;

	public Text scoreText;


	// Use this for initialization
	void Start () {

		PlayerPrefs.GetInt ("High Score");

		IntializeVariables ();

		TKOCount = 0;
		scoreCount = 0;

	}
	
	// Update is called once per frame
	void Update () {



		if (scoreCount <= 0) {
			scoreCount = 0;
		}
			

		if (scoreCount > highScoreCount) {
			highScoreCount  = scoreCount;	
			SaveHighScore ();
		}

		scoreText.text = " " + scoreCount;
		TKOText.text = " " + TKOCount;
		toothCount = scoreCount * .10f;

		SaveScore ();
		SaveGoldTeeth ();




}
	void SaveTeeth(float teeth){

	}

	void SaveHighScore(){
		
		PlayerPrefs.SetInt ("High Score", highScoreCount);
		PlayerPrefs.Save ();
	}

	void SaveScore(){
		
		PlayerPrefs.SetInt ("Score", scoreCount);

	}

	void SaveGoldTeeth(){
		PlayerPrefs.SetFloat ("Tooth Score", toothCount);
		PlayerPrefs.Save ();
	}

	void IntializeVariables(){
		if (!PlayerPrefs.HasKey ("Game Initialized")) {

			PlayerPrefs.SetInt ("Score", 0);
			PlayerPrefs.SetInt ("High Score", 0);
			PlayerPrefs.SetFloat ("Tooth Score", 0);

			PlayerPrefs.SetInt ("Game Initialized", 123);

		}
	}

}

Any help is appreciated!

void Start(){
highScoreCount= PlayerPrefs.GetInt(“HighScore”);
}
And when u check ur score :
if(scoreCount>highScoreCount){
PlayerPrefs.SetInt(“HighScore”, scoreCount);
PlayerPrefs.Save();
}
