Andy, you are correct in that the seller's ad is misleading by referring to the chip on page 147 in the C-W book. The chip is actually listed on page 277. This seller was not knowledgeable about collecting terms. He did not know that the mold was zigzag until I told him. It is possible that he looked under the Silver Slipper on the strip and the only ZIGZAG 25 he found was the 6000.00 one. I doubt if he knows what inserts or inlays are. However, both James and I told him that the chip was worth somewhere between 300.00 & 1200.00. I suspect that he knew that the 6000. value was not correct for his chip. I knew from speaking to him that he was going to get as much as possible for his chip. I am sorry to see that he found a person who was not only uninformed but did not take the time or effort to research the chip.
