21,000 chips were delivered to Mason & Co. in Newark NJ in 1934. From what I gather 300 is the normal roulette order per table color. If my math is right then 70 different roulettes were ordered. Maybe it was a refill order of 150 per color. That would indicate 20 tables (140 different chips). USPC records show a table 20.

Aside to John Benedict. I think there are more Foreign Clubs than there are Country Club de Limas.

I know of no other Foreign Club besides the one in Tijuana. Although delivered to Jersey, Mason was a national distributor.

Off hand it seems to me that the casino/club must have been quite large to support 20 tables.

I'm leaning toward attributing these chips to Tijuana. Anyone agree or disagree?

As I did with the CA Albert attribution, some nice chips will be on your way if you can provided a preponderance of evidence to support an attribution for these chips.
