I just noticed that this chip sold on ebay for $228.

That particular chip had some smaller chips on the front and a large chip on the back. I think my chip has a sharp rim with absolutely no chips or dings. 99%+ of the cross hatching is there.

I think best offer over $254.99 would be fair. Priority included.

Of course I would rather trade for ivory or crest & seal. I reserve the right to end the auction whenever.
