How would I make a ship spawner that will take away Coins when clicked?

This should work. If this does please accept my answer as the solution :)

local ServerStorage = game:GetService("ServerStorage")

local detector = workspace["Regen Speedboat 50 Coins"]
local debounce = false

local SHIP_COST = 50--Coins cost

script.Parent.ClickDetector.MouseClick:Connect(function(player)
    if debounce then
        return
    end
    debounce = true
    print("I was clicked!")

    local coins = player.leaderstats.Coins

    if coins.Value >= SHIP_COST then
        coins.Value -= SHIP_COST
        local Copy = ServerStorage:FindFirstChild("SpeedBoat"):Clone()
        Copy.Parent = workspace
        Copy.Name = "Speedone"
        Copy:MoveTo(Vector3.new(-14, 2.5, -344))
    end
    wait(6)

    debounce = false
end)
