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.
