This chip was sold to me as being from the Sahara Reno and the logo is the same as shown on the 25c chip in Campiglia & Wells' book (2nd ed. p.224) The logo is also noted in TCR as being on the 10c & 25c chips. This is a $1 chip, off-white with small key mold. It is not mentioned in either catalog. Is it a chip that was manufactured but never used at the casino? or a fake? If anyone can enlighten me with the history of this chip I would be very appreciative.
