How do I load my saved data?

this is the code I have so far

local DS1 = game:GetService("DataStoreService"):GetDataStore("Coins")
local DS2 = game:GetService("DataStoreService"):GetDataStore("Gems")
local DS3 = game:GetService("DataStoreService"):GetDataStore("equippedKnife")
local DS4 = game:GetService("DataStoreService"):GetDataStore("equippedGun")

game.Players.PlayerAdded:connect(function(player)

    local stats = Instance.new("IntValue", player)
    stats.Name = "leaderstats"

    local coins = Instance.new("IntValue", stats)
    coins.Name = "Coins"
    coins.Value = 50

    local gems = Instance.new("IntValue", stats)
    gems.Name = "Gems"
    gems.Value = 0

    local inGame = Instance.new("BoolValue", player)
    inGame.Name = "InGame"

    local equippedKnife = Instance.new ("StringValue", player)
    equippedKnife.Name = "equippedKnife"
    equippedKnife.Value = "Default"

    local equippedGun = Instance.new("StringValue", player)
    equippedGun.Name = "equippedGun"
    equippedGun.Value = "Default"

    while wait(60) do
        DS1:SetAsync(player.userId.."_DS1", coins.Value)
        print("Saved Coins")
        --Saved Coins
        DS2:SetAsync(player.userId.."_DS2", gems.Value)
        print ("Saved Gems")
        --Saved Gems
        DS3:SetAsync(player.userId.."_DS3", equippedKnife.Value)
        print ("Saved knifeEquipped")
        --Saved equipped Knife
        DS4:SetAsync(player.userId.."_DS4", equippedGun.Value)
        print ("Saved gunEquipped")
        --Saved equipped Gun
      end
end)

how would I load the stats everytime rather than just saving it?
