Ok so the first argument on an OnServerInvoke function is always the player who called InvokeServer(). You can then get the name of the player from the first argument rather than passing the player's name along with the player. Also since you used :FindFirstChild() on a userdata value instead of a string, it returned a nil value.

function MakeSureCoinsAreNotHacked.OnServerInvoke(Player) -- Player is always the first argument
local PlayerName = Player.Name -- Get the player's name
local PlayerFile = script.PlayerStats:FindFirstChild(PlayerName)
local PlayerCoins = PlayerFile.Stats.Coins 
return PlayerCoins.Value

local MakeSureCoinsAreNotHacked = MakeSureCoinsAreNotHacked:InvokeServer()
