Standard baccarat chips are 43 mm in diameter. The only exception I've found in Nevada is Harrahs brass, which was 44 mm.

Harrahs seemed to like odd sizes. Their first dollar token in 1965 was 40 mm rather than the standard 37 mm in diameter. They only did it the one year, as did a couple of Las Vegas clubs.

I haven't tried to find a holder for baccarat, but there should be plastic rings that fit the 43 size to an air-tite holder.
