How to fix cloned object overlapping parts on there spawn plate?

Help and Feedback Scripting Support

I have this coin spawn system that spawns coins on a part by detecting the size of the part. But there are also other objects on that part and those coins are overlapping with each other. Is there any way to stop them from overlapping such as making a group of part names that it won’t spawn near?

This is my current script that spawns the coins

local coin = game.ServerStorage.exp-- Path to coin
local amountCoins = 0
local maxCoins = 20

while true do
	task.wait()
	if amountCoins >= maxCoins then continue end
	local clone = coin:Clone()
	clone.Parent = game.Workspace
	local Baseplate = workspace.Baseplatep1
	local Size = Baseplate.Size
	local Pos = Baseplate.Position
	local CoinHeight = 2 -- You can choose
	local X,Y,Z = math.random(Pos.X - (Size.X/2), Pos.X + (Size.X/2)),Pos.Y + 
		CoinHeight,math.random(Pos.Z - (Size.Z/2), Pos.Z + (Size.Z/2))
	local SpawnPos = Vector3.new(X,Y,Z)
	clone.Position = SpawnPos
	amountCoins += 1
	clone.Destroying:Connect(function()
		amountCoins -= 1
	end)
	task.wait(20)
end
