Clicking Script-

local CanUse = true

script.parent.Equipped:Connect(function(mouse)
    mouse.Button1Down:Connect(function()
    if not (CanUse) then return end
        player.leaderstats.Sips.Value = player.leaderstats.Sips.Value + 1
    CanUse = false
    wait(1)
    CanUse = true
    end)
end) 

Leaderstats-

game.Players.PlayerAdded:connect(function(p)
    local stats = Instance.new("IntValue")
    stats.Name = "leaderstats"
    stats.Parent = p

    local money = Instance.new("IntValue")
    money.Name = "Sips" -- Change "Money" to anything you want to name it like "Cash"
    money.Value = 0 -- Change the value to how many you want when the player joins the game
    money.Parent = stats


    local Cash = Instance.new("IntValue")
    Cash.Name = "Cash" -- Change "Whatever" to anything you want to name it like "Cash"
    Cash.Value = 0 -- Change the value to how many you want when the player joins the game
    Cash.Parent = stats

end)

Sell Part-

local Part = script.Parent
Part.Touched:Connect(function(HIT)
    local H = HIT.Parent:FindFirstChild("Humanoid") 
    if H then
        local player = game.Players:GetPlayerFromCharacter(HIT.Parent)  
if player then
    local leaderstats = player:WaitForChild("leaderstats")
    local Currency = leaderstats.Cash -- Change Money To your currency
    local Selling = leaderstats.Sips -- Change Grass to what you selling.
        if Selling.Value > 0 then
            Currency.Value = Currency.Value + Selling.Value *1 -- This 1 means multiple you can change it to whatever you want
            Selling.Value = 0
        end
end
