Here`s Classes

class GameSprite(sprite.Sprite):

        self.speed = speed 
        self.image = transform.scale(image.load(filename), (w, h)) 
        self.rect = self.image.get_rect() 
        self.rect.x = x 
        self.rect.y = y 
        self.w = w 
        self.h = h 
 
    def reset(self): 
        window.blit(self.image, (self.rect.x, self.rect.y)) 
 
    "GameSprite logic"
 
class Coin(GameSprite): 
    def __init__(self, filename, x, y, speed, w, h): 
        GameSprite.__init__(self, filename, x, y, speed, w, h) 
        self.counter = 0 
        self.isPicked = False 
        
    "Coin Logic"

Error
coin_ex = Coin(“Coin1.jpg”, x * TILE_SIZE, y * TILE_SIZE, 10, 16, 16)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: ‘Coin’ object is not callable

I tried using call method, but it didnt worked, i dunno why
