This marble may not be unusual at all to you collectors but its the only one I've seen like it. Below is the collection of marbles that we had collected up at my parents house. A few may have been theirs orginally but alot of them were found over the years while arrowheading hunting plowed fields. The one in particular was my most recent find 4-5 years ago on a rocky creek bank while doing a canoe trip. It looks like china without the glaze and has a pretty blue flower design with bands running around it. Can you pros tell me what it is? Are any of the other marbles collectible. None are for sale I just would like to know their historical background. thanks in advance.
