attempt to compare number <= boolean any way I can overcome this?

Hello, I have a shop script that gives speed, however I want to make a speed cap on the shop and I get an error (title)

local speedcap = 50
elseif item == "Speed" then
			if not player.Speed.Value >= speedcap then
			player.Speed.Value = player.Speed.Value + 5
				player.Character.Humanoid.WalkSpeed = player.Speed.Value
				player.leaderstats.Coins.Value = player.leaderstats.Coins.Value - price
				return true
			end

Is there any way to overcome this? Any help is appreciated!
