	public int X = 0;


	// Use this for initialization
	void Start () {
	
	}
	
	// Update is called once per frame
	void Update () {

	}

	void OnMouseDown() {
	if (gameObject.tag == "element") {

			Destroy(this.gameObject);
				}

The way you’ve declared your variables, each Coins script has its own cointext, curCoins, maxCounts, and X.

Some of those values might make sense in another component (is “score” really a notion each coin should track, or is “score” something each player has?).

The following is just an example; it assumes that you have a GameObject named “Player” with a “PlayerScript” component that exposes a public function “GetCoin”. We don’t need to know what exactly GetCoin does, but we can probably assume that it increases the player’s score.

void OnMouseDown() {
    GameObject player = GameObject.Find("Player");
    PlayerScript playerScript = player.GetComponent<PlayerScript>();
    playerScript.GetCoin();
    
    Destroy(gameObject);
}

As an alternative, you could declare some of those as static fields:

static int score;

That way, the score field is shared by all instances of the Coin class. If other scripts need to access this data, you’ll need to expose it publicly (consider making it read-only).
