I think I see a yellow, brown, green, flip-flop, with the yellow on one side pushed up against the green on the other. Jumpin' Jiminy man, that's a nice marble! Too nice for a Kokomo, IMO. Is that an elusive Green Sunset, maybe burnt a bit?
. . . a fellow Hoosier found another. I think Kokomo marbles are interesting and great fun to collect. No doubt, they are much less common than Pelts, but I doubt I have seen half a dozen I would call pretty. The vast majority wouldn't even come close. But that is just fine with me because I don't really care for marbles that are too flashy - unless they are WV swirls, of course.
BTW, I think the middle one in the group of three could be a Kokomo too.
They are all nice but that red, white and blue one in the 'unknown' group is very interesting, and the RWB in the last shot is great. I'd like to see more pics of them!
