These $1 chips are from the Crystal Bay Club in Lake Tahoe, NV. The chip on the left appears to be TCR# N5048, Cream colored, SMKEY mold, HS Gold. The chip on the right is the same in all respects, except that there are tiny green specks throughout the chip. This variation is not in TCR #7. When I first got the chip, I thought it was dirty. But under a magnifying glass you can clearly see the green specks. If anyone would like a higher resolution scan of the chip, just email me.
