Identifications and information are accredited to members of the WVMCC and the marble collecting community. Special credit noted to marble Archaeologist, overall marble enthusiast and co-founder of our club, Mr. Ron Shepherd. Ron also provided many marble specimens for photographic reference here. Additional credit to Dean Six, Susie Metzler, and Michael Johnson for their publication 'American Machine-Made Marbles'. An unparalleled reference to the history of glass marble manufactures that is loaded with much more information than presented here, and a must have for the serious collector.
