I bought a large collection of marbles from a  Ritchie County digger.  Lots of dugs but lots he picked up at yard sales, consignment shops, etc.   These are all UV.   Those 2 w/ purple base and green swirls are Jabo.  A few of these are probably Champion.   One looks like it could be Davis but I don't want to say it is because I am not sure.   Look at pictures and ask questions if needed.   From 9/16"-13/16".   A few a tad out of round. Please review feedback going back over 24 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 dissatisfied with any purchase.
