Indeed, a T. So I searched again in Menzel and found the following in the section "without place name":
44441.1 T
Al, 24,0 mm, o.J., Rs. "GUT FÜR (WZ) LITER BIER"
Metal and size the same but with a different reverse (Rs)
Unfortunately it is not mentioned whether the T is in a Latin or Gothic letter.
Thanks Mal!
