The Mint Chocolate Chip is one very hard to find(and expensive) marble.   As seen on the YouTube Heaton Identification video with David Tamulevich they made the Mint Chocolate Chip marble and also the same color marble minus the brown or so called chocolate chip.   So David called these kind just "Mints".  If they had the brown they would be the "Mint Chocolate Chip".  These 6 Mints are 19/32" mintminus to nearmint.     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 dissatisfied with any purchase.
