An auction on eBay just ended for 4 of these chips for over $200. I was able to get a couple dozen of these from the seller for anyone who is interested.

These are new to me. I had a grey chip, but this one is definitely BLACK.

Price is $35 each (postage included). The chips are in near mint condition.

You can Paypal to edhertel@comcast.net or email for options.
