Seems there are certainly some out there, but not going to be an easy project.
Spinettis seems to have a handful of them to get you going, but I don't imagine you'll be finding these in quantity without some very alluring trade bait.
Some background information :
Diamond Tooth Gertie’s Gambling Hall
was “ Canada’s first casino “ - opened
in 1971 .
The TRK small crown chips were ordered
in 1974 and 1978 .
Very cool chips - IMHO
Making some serious headway, could still use around a rack of the Blue $1s and a few barrels of the 25c off-white chips. Only need a handful of the yellow $5s!
