Is there a better script for permanently deleting items?

So iv been working on a game for awhile now and i'm just getting to making some levels and i have a currency system so i'm making it so the players can collect them threw out the various levels now i have a problem thou as i could just have them respawn in every time i had hoped that they would just delete and be gone so here is the script i used

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using TMPro;
 
 public class PickupMoney : MonoBehaviour
 {
 
     void Start()
     {
         
     }
 
     public static class PlayerData
     {
         private const string playerScoreHash = "score";
         public static int Score
         {
             get
             {
                 return PlayerPrefs.GetInt(playerScoreHash);
             }
             set
             {
                 PlayerPrefs.SetInt(playerScoreHash, value);
             }
         }
     }
 
 
 
 
 
     public static class CoinPickup
     {
         private const string CoinPickupA = "coind";
         public static int coind
         {
             get
             {
                 return PlayerPrefs.GetInt(CoinPickupA);
             }
             set
             {
                 PlayerPrefs.SetInt(CoinPickupA, value);
             }
         }
     }
 
     public GameObject coin;
 
     void Update()
     {
         if (CoinPickup.coind == 1)
         {
             Destroy(coin.gameObject);
         }
     }
 
 
     void OnTriggerEnter(Collider obj)
     {
         if (obj.gameObject.tag == "Player")
         {
             PlayerData.Score += 5;
             CoinPickup.coind = 1;
         }
 
     }
 
 }

But if i used this script i will have to make a new player pref each time is there any way i can make this more efficiently
