Here is a toll I picked up in an antique mall a couple of weeks ago. The embossing is pretty faint, but it still has some quirks. The "o" in "Co" is raised, with no visible period beneath it, unlike the other toll insulator which I posted a while back. However, there appears to be a faint period after "AM". The overall shape of the piece indicates (at least to me) that it is older than the toll I posted. Embossing: AM(.) TEL & TEL Co (no period). Dome: Backwards "5", as well as a "5" centered with the text on the crown.
