I have a 25 cent chip from the Fremont in Las Vegas. It's orange and has Sam Boyd's on it and it's just like the one listed in The Chip Rack #N0278 BUT it's a silver hot stamp not gold. It doesn't look like it started out as gold and has worn off to a silver finish but I'm not sure. My scan (unfortunately, not the best) shows both the silver hot stamp chip in question and a gold hot stamp chip. Can anyone provide information about this chip? Thank you.
