Script is changing both leaderstats to the same one when saving. How do I fix this?

So I'm trying to make a script that makes two leaderstats, Coins, and Level, but the problem that keeps happening is when the coins is changed, lets say the coins value was changed to 100. Then once I rejoin and the datastore saves my progress, it changes Level to the same amount as the coins, so basically the coins are 100, and the level is 100. Heres my code:

local dsService = game:GetService("DataStoreService")
local ds = dsService:GetDataStore("MondStats") 

game.Players.PlayerAdded:Connect(function(plr)
    local folder = Instance.new("Folder", plr)
    folder.Name = "leaderstats"
    local currency = Instance.new("IntValue", folder)
    currency.Name = "Coins" 
    currency.Value = ds:GetAsync(plr.UserId) or 0
    currency.Changed:Connect(function()
        ds:SetAsync(plr.UserId, currency.Value)
    end)
    local currency2 = Instance.new("IntValue", folder)
    currency2.Name = "Level" 
    currency2.Value = ds:GetAsync(plr.UserId) or 0
    currency.Changed:Connect(function()
        ds:SetAsync(plr.UserId, currency.Value)
    end)
    currency2.Changed:Connect(function()
        ds:SetAsync(plr.UserId, currency2.Value)
    end)
end)

game.Players.PlayerRemoving:Connect(function(plr)
    ds:SetAsync(plr.UserId, plr.leaderstats.Coins.Value, plr.leaderstats.Level.Value) 
end)
