I picked up an old lot of marbles. I've identified many but there are a few(especially this one) that have me scratching my Mellon. I've heard of wooden marbles, never had one though. This guy is big. There is a flat spot kind of like the eyes that Benningtons have, which is odd if this is wooden. I've looked up Gutta Perchas but doubt this is one because of the one colour... Unless it's unfinished? Sorry but size comparison is a standard sized marble, and thanks for any help guys
