I've looked on and off for this particular CD 121 Am Tel toll, and am re-igniting the search.

The price guide lists this as EIN005. Lists it only in light green aqua. AND lists it as having a dome number that is INCUSED instead of EMBOSSED. The assumption being the dome number is an "inny" instead of an "outy" in terms of whether it rests above or below the plane of the dome glass surface.

As always, hoping for VNM+. I've never seen a photo of this particular CD 121 Am. Tel. toll, so details on the incused mold number are general. i.e., is the actual number recessed into the dome glass, or is the mold number within a recessed "area," like a circular spot? Don't know for sure. If anyone has this and wants to sell, hit me up with the details. If you have one and don't want to sell, I'd still love to see a photo of the incused dome area, so I can answer the above question for the future.

Thanks for looking.
