~~~ light coated paper stock in the same way you would wrap a stack of coins and placed the rolls in their boxes.

Upon unwrapping the first roll of the Floridian "50" Casino chips I noticed a white powder thinking it was talcum. Someone mentioned it was silica and I assumed it was an agent to absorb moisture.

Not sure for how long the paper wrapped rolls procedure lasted but, the whole box of the Floridian chips were that way (powder) as were 7 or 8 stacks of the CAL-NEVA "Pine Cone" Roulettes which, I did not notice until Gene Grossblatt phoned me after he received his set of 12 chips saying that they were unused and still had traces of the powder on them...
