"Corals" are an argument type for sure. This is a collectors name as far as I know and no company marketed them as such imho.
Several companies made them, including Champion, Alley and CAC and a few made them that did not intend on this color. They can vary quite a bit in coverage and base color such as transparent vs almost opaque and opaque as well.
Zaboo posted some great imagesā(really great images) I just love them for sure! Zaboo was around when I was a rookie and I hope to see some more of this respected collectors' takes on the IDās on this format, along with some more great images.
I just collect anything that looks like it has a ācoralā color to it and I could care less what company made them. (I suck at WVS ID, try and failābut keep on going)
The color is the thing to meānot the value.
Here are a few that I have collected over the years.
MarbleāOn!!
