How do I make a touched part return back to it's original Vector3?

I am making a simple Cash leaderstats thing which works based off of parts called coins that are each colored differently. Each are colored colored for bronze, silver, and gold. Each coin works as far as giving their correct value and etc. The only real problem is that I don't know how to make them go back down(as when they're touched they're Vector3's y axis goes up).

script:

for i,v in pairs(game.Workspace:GetChildren()) do
    if v.Name == "Coin" then
        v.Touched:connect(function(hit)
            C = hit.Parent.Name
            lel = game.Players:FindFirstChild(C)
            if lel then
                Cash = lel.leaderstats.Cash
            end
            if v.BrickColor == BrickColor.new(106)then
                Cash.Value = Cash.Value + 5
                wait(.1)
                v.Transparency = 1
                wait(10)
                v.Transparency = 0
                wait(1)
            end
            if v.BrickColor == BrickColor.new(329)then
                Cash.Value = Cash.Value + 10
                v.Transparency = 1
                wait(10)
                v.Transparency = 0
                wait(1)
            end
            if v.BrickColor == BrickColor.new(24)then
                Cash.Value = Cash.Value + 15
                v.Transparency = 1
                wait(10)
                v.Transparency = 0
                wait(1)
            end
        end)
    end
end
