Found these at a neighborhood yard sale here in Hillbilly Heaven. Best part is that I didn't even have to pay face value! I don't have any price guides on foreign chips and sure would be interested if any of them are worth more than a few dollars especially the Isla Verde and Palace chips. I also am curious about the MGM Grand chips. The lions are the same size but they are two different types of chips. On one chip the lions hair is very distinct and on the other it can hardly be seen. On the darker chip the brass shavings are very evident and I don't see any shavings on the other chip at all. Are there two variations of this chip?
