The West Virginia Museum of Glass has marbles on display but I think they are mainly marbles and not much, if any, marble related items. Some years back, there was a National Marble Museum in Yreka, California but it closed down and all of the donated marbles and marble related items were shipped to the WV museum. I am guessing a lot of it is still in storage. Lee's Legendary Marbles in York (?) Nebraska is another locations with a lot of marbles and marble memorabilia.
