Chips are real and were used at the "French" single zero roulette tables at Paris in LV.

They came in 3 varieties Plain, W/Stripes and W 4 Tabs
The denominations were $5 Red $10 Blue $20 Green
There were only 2 Varieties of the $50 [Purple] and $100 [ White ] Plain and with Stripes.
Starting with the $100 denomination the size of the Jeton was also larger.
There were higher denomination also, I know of a $500 and I'm sure there were higher ones also but am not sure of colors or sizes
