How do I make different coins different points?

I can't figure out how to make different coins wreath different points to the score

Coin = class 
  constructor = function( str, val, pos_x, pos_y )
     this.nane = str
     this.value = val
     this.x = pos_x
     this.y = pos_y
  end
end
     
Player = class
  constructor = function()
     this.coinA = 100
     this.coinB = 200
  end
  setCointA = function(  value )
     this.coinA += value
  end
  setCoinB = function( value )
     this.coinB += value
  end
  setCoin =  function( coin ) 
     if coin.name == "A" then 
        this.setCoinA( coin.value )
     else
        this.setCoinB( coin.value )
     end
  end
  collide = function( coin )
  // 
  end
end

init = function()
  player = new Player()
  coins = []
  coins.push( new Coin("A", 123 ))
end

update = function()
  coins.forEach( function( coin )  
     if player.collide( coin ) then player.setCoin( coin ) end
  end )
end
 

Thanks :)
