I received an old glass cookie jar full of my deceased father in laws childhood marbles, he played when he was youngster. He graduated high school in 1958 so I am guessing that the marbles are from the late 1940's. I have done a little research on some of them and see that there maybe a few of substantial value. Is there anyplace in Ohio I can have them looked at by someone with more knowledge about them? Any help will be appreciated. I have attached a few pictures of some of them, there are more.
