I talked to the guy last Sunday who is selling the Double O. O. Chips. Has sold 2 on eBay $155 and $143 and a 2nd chance for $153. I got mine for way less. He's just a seller, not a collector. He said he started with 15 of them. So...that is 4 (known) sold so far. Just keep count of how many sell and you should be able to get one of the last 4 or 5 for less than $75.
