This seller is a club member. To quote the seller's auctions:

I HAVE BEEN A COLLECTOR MOST OF MY LIFE..YEARS AGO WITH COINS, STAMPS,LLADROS, AND BASEBALL CARDS.. I AM CC & GTCC MEMBER 5854 AND ALWAYS TRY TO TREAT MY CUSTOMER AS I WOULD LIKE TO BE TREATED..IF YOU ARE NOT HAPPY, THEN I AM NOT HAPPY.. PLEASE CHECK MY FEEDBACKS...THNX ..WALLY

I would suggest just emailing the seller and advise him of the recent information that has been brought to light. I'm sure being a club member, he would be more then happy to correct the auctions once he is informed of the real story with these chips.
