Wasn't it Bull Durham in Colorado did the same thing? The numbered/limited chips will be more valuable. Unless nobody buys the new chips and they get pulled and destroyed. Either way it's a clear variation. If they were trying to scam you into adding another $25 chip to your collection with this ploy, maybe it'd be different. I think it's fun when a variation on a $1 shows up. Heck, John's Nugget has 5!
