that there is a bunch out there right now. Two years ago, I bought & sold that same issue chip for around $100...the latest one I purchased about three weeks ago for about $30 in the same shape as the one you show. I think that there's a bunch that have been found or are coming out & the much lower pricing reflects that. My recollection is that the chip you show is listed in the 10th edition of The Chip Rack with a $250-$300 value -- we'll have to wait & see what the 11th edition has it priced at.
