I know nothing about when or where these chips were produced, I am far from an expert. However, the website at the following link shows that you knew these were for the one in Canada. You are credited with providing the photos of the chips. Am I wrong that after providing the photos of the chips for the Canadian Silver Slipper page, you then sold those same chips on ebay as though they were from Las Vegas. Is it your case that both silver slipper's used the exact same $1 chip? Just my 2 cents.
