Most of the time imho--
I will always look to see if the possibility of CAC is present—facts are that Akro Agate made some pretty nice slag’s that will one time or another—resemble those of all makers----all makers----imho .
The CAC thing and owning one will always be a search that is pursued.
You, she/he will find one sooner or later—keep up the hunt and of course---as we all know--CAC marbles do not grow on trees--they are just a rare thing that we all pursue and wish for as “Machine Made Marble Collectors”.
Keeeeeeeeep up the search, do the research, research, research, and----as always—
Marble—On!!---For sure!!
