My parents moved into the house in 1948, there was a log cabin there before the house. A few years ago floors were torn out and my nephew scratching around found some marbles and gave me these. The one in the center is over 1 1/4 inch and clay. It kinda has orange peel effect like the napkin it is on and is not shiny or glazed. You can see lines like clay connecting when being smushed together. The other one looks like clay but has a glaze or is shiner then the big one and smooth. Can any one tell me any thing about any of these, how old and what kind? Thanks
