They are real BJ chips.
This was not an easy one to research! The Casino Sadsh chips were sold to a Company called Amusement Populaire in Montreal, Canada. They were for a Charity Casino. They have purchased quite a few of these chips from us. I will give you some minimum quantities of the chips that were purchased. Keep in mind they have purchased probably more than this. It is not possible to get the exact quantities. They were purchased over 10 years ago!

$1=10,100
$2.50=4100
$5=15,100
$10=20,100
$20=18,100
$50=4000
