When the player touches a coin, the score goes up but the coin doesn’t disappear.

Here is the CoinScript:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CoinScript : MonoBehaviour {
 private LevelManager gameLevelManager;
 public int coinValue;
	// Use this for initialization
	void Start () {
	gameLevelManager = FindObjectOfType<LevelManager> ();	
	}
	
	// Update is called once per frame
	void Update(){}
  void OnTriggerEnter2D(Collider2D other){
  if (other.tag == "Player")
  {
  gameLevelManager.AddCoins(coinValue);
      Destroy (gameObject);
  }
 

		
	}
}

Here is the LevelManager:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class LevelManager : MonoBehaviour {
public float respawnDelay;
public PlayerController gamePlayer;
public int coins;
public Text coinText;
	// Use this for initialization
	void Start () {
	gamePlayer = FindObjectOfType<PlayerController>();	
	coinText.text = "Coins: " + coins;
	}
	
	// Update is called once per frame
	void Update () {
		
	}
	public void Respawn(){
		StartCoroutine ("RespawnCoroutine");
	}
	public IEnumerator RespawnCoroutine(){
	gamePlayer.gameObject.SetActive (false);
	yield return new WaitForSeconds (respawnDelay);
	gamePlayer.transform.position = gamePlayer.respawnPoint;
	gamePlayer.gameObject.SetActive (true);
		}
		public void AddCoins(int numberOfCoins){
			coins += numberOfCoins;
			coinText.text = "Coins: " + coins;
		}
}

I am new to all of this.,When I run the game, the score goes up when the player touches a coin. But for some reason, the player goes through the coin and the coin stays on screen.

Here is my CoinScript:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CoinScript : MonoBehaviour {
 private LevelManager gameLevelManager;
 public int coinValue;
	// Use this for initialization
	void Start () {
	gameLevelManager = FindObjectOfType<LevelManager> ();	
	}
	
	// Update is called once per frame
	void Update(){}
  void OnTriggerEnter2D(Collider2D other){
  if (other.tag == "Player")
  {
  gameLevelManager.AddCoins(coinValue);
      Destroy (gameObject);
  }
 

		
	}
}

Here is my LevelManager:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class LevelManager : MonoBehaviour {
public float respawnDelay;
public PlayerController gamePlayer;
public int coins;
public Text coinText;
	// Use this for initialization
	void Start () {
	gamePlayer = FindObjectOfType<PlayerController>();	
	coinText.text = "Coins: " + coins;
	}
	
	// Update is called once per frame
	void Update () {
		
	}
	public void Respawn(){
		StartCoroutine ("RespawnCoroutine");
	}
	public IEnumerator RespawnCoroutine(){
	gamePlayer.gameObject.SetActive (false);
	yield return new WaitForSeconds (respawnDelay);
	gamePlayer.transform.position = gamePlayer.respawnPoint;
	gamePlayer.gameObject.SetActive (true);
		}
		public void AddCoins(int numberOfCoins){
			coins += numberOfCoins;
			coinText.text = "Coins: " + coins;
		}
}

  1. private void OnTriggerEnter2D(Collider2D other)
  2. if (other.gameObject.tag == “Coins”)
    {
    Destroy(other.gameObject);
    }
    //Put this on the player script
