I guess these could be Bogart.   They were dug on the Heaton site and in the same area. .   Mintminus.   9/16"-19/32".       Please review feedback going back over 23 years at the same E-Bay location.  I  have spent hours researching old WV marble companies and as a social worker traveling  the backroads of WV  providing counseling services to children and their families.   Many of the people I worked with had marbles or knew someone who did.  What started as a hobby grew into an E-Bay enterprise.   I got permission from owners and dug 10 different WV old marble sites from Ravenswood to Clarksburg.  So I have many, many marbles.   Send me an E-Mail for your marble needs.   I answer all respectful questions.  Shipping ALWAYS combined when possible.   Please wait for  combined invoice if purchasing multiple items.  A proud USAF Veteran offering honest services and speedy delivery.  Please contact me if dissatiffied  with any purchase so I can make it right.
