I appreciate your thoughts! We are all trying to learn more about what we love; marbles. I definitely agree that some marbles are considered a specific ātypeā or have a specific name, but that doesnāt mean they are equally desired by collectors. Marble-on!!
Even though there is some āfeatheringā in the second photo, I donāt think it is as fine and delineated as it should be for a Peltier. I think it is Akro, IMHO.
