...........made for possible use with an Auto Sort Roulette machine but as far as I know they were never used on the Roulette Tables at Bally's Park Place for regular play. They came in 8 colors as shown in your post. These Plastic chips made by Bud Jones are less common than the Regular Park Place Series -III Roulettes that are Paulson Roulette Mold clay chips. Only #1 chips are known of these Bud Jones chips while the Paulson chips exist in #1 - 8, 10, 11, 12, 14 and 17.
I have this set of 8 chips listed on page 72 of my R.I.C.H. CATALOG AND CHECKLIST OF ATLANTIC CITY ROULETTE CHIPS that I published way back in 2002 and revised in 2004.
Take care,
