I have recieved a chip that i cannot find in the Official U.S. Casino Chip Price Guide. The chip in question is a mustard .25 cent hot stamp {no name on chip ,just the 25 hot stamp} NEVADA mold that i was told ,was removed from the SILVER CITY by this person many years ago. My question is since in the book there was a .50 cent varient and sometimes the casinos did not use they're name on the chip , is there any chance this is truely from the SILVER CITY CASINO or was I misled.??? Thank you in advance for any information.
