Does anyone recognize the chip shown here? The reverse is $.50. I would normally consider this as one of the many unknown monogrammed chips except that the Gaming Table lists a CS chip as being from the Crystal Saloon in Virginia City. It shows the same design (the S inside of the C) but with a different mold. The Chip rack lists only one chip from that casino and it has a small key mold. Does anyone know if this is the same style of CS as the chip from Virginia City?
