I don't see how this seller, who has also gone to private listings, can claim he did anything but made a simple mistake listing the chip? Someone with integrity would back up their items as being the same thing they claimed to be selling.

This is also clear enough in a question from a buyer.

Q: does this chip have 666 or 999 on the other side of the chip? can you post a pic of the other side. Nov-09-08
A: The picture that is posted is the Chip up for Auction. If 1 Picture is Posted, then both sides are the same.

Easy question which unlike the rest, you may decide to answer instead of dodging.

If it wasn't the same on both sides Mr. Mosquito, how can you not offer a refund? Is it the same on both sides or not?
