I guess it depends on what you expect from them. They're most likely the same quality or maybe of a lesser quality than the "Dice" chips. I wouldn't get them personally because there's virtually no information on them except, "this box is heavy". Who knows (I certainly don't), they might be great chips.
Bidding is over though, are you the one that bought them?
If anything they are going to be like the Diamond chips. I would have to say they look better then the dice chips for sure but remember its all in the eye of the bidder. If they are not clay and you like them when they come in great you got a good deal. If not make a travel set so that when you get pissed off if you loose you can throw them against the wall and still feel good about it.
WOW! Got them today, and they are clay, and feel great. Brand new with sharp edges. Im gonna see if i can find more and make a set out of them, i LOVE them.
