Without a single word showing they were Roulettes.
They only had one purpose in the casino and that was on the Roulette table and they're non-denominated and cannot be used for any other game and they are not the type jeton that was used on a French Roulette where that had denominations and could have been used on any other game like at Paris Las Vegas. These are strictly Roulettes; non-denommated Roulettes and have been known as Roulettes from way back when author and Master Historian Tom Stroh told us they were Roulette jetons.... Though, of course, it is up to ChipGuide to decide what to call them and, all I did was to make a suggestion and provide documentation.
