Player currency not saving in DataStore?

Hello again, I am using the DataStore service to save a player's money. There are no errors in the output, but the amount of cash I enter in the value doesn't save. Again, I am using AlvinBlox's tutorial. Here is the entire code:

local CurrencyName = "C01nz"
local DataStore = game:GetService("DataStoreService"):GetDataStore("TestDataStore")

game.Players.PlayerAdded:Connect(function(player)
    local Folder = Instance.new("Folder")
    Folder.Name = "leaderstats"
    Folder.Parent = player

    local Currency = Instance.new("IntValue")
    Currency.Name = CurrencyName
    Currency.Parent = Folder

    local ID = CurrencyName.."="..player.UserId
    local SavedData = nil

    pcall(function()
        SavedData = DataStore:GetAsync(ID)
    end)

    if SavedData ~= nil then
       Currency.Value = SavedData
        print("Data loaded.")
    else 
    -- New Player1!!111
       Currency.Value = 0 
       print("A new player")
   end

end)


game.Players.PlayerRemoving:Connect(function(player)
    local ID = CurrencyName..":"..player.UserId
    DataStore:SetAsync(ID,player.leaderstats[CurrencyName].Value)
    print("Data Saved")

end)

game:BindToClose(function()

    --When game is ready to shutdown
    for i, player in pairs(game.Players:GetPlayers()) do
       if player then
        player:Kick("This game is shutting down.")
        end
    end
    wait(5)

end)

There are no errors in the output, and I looked at the tutorial numerous times, so I am really stumped. Help would be appreciated.
