This may be a surprise to you, as it was to me, but there are more Catholic churches in Las Vegas than casinos. Not surprisingly, some worshippers at the Sunday services will give casino chips rather than cash when the basket is passed. Since they get chips from many different casinos, the churches have devised a method to collect the offerings. The churches send all their collected chips to a nearby Franciscan monastery for sorting, and then the chips are taken to the casinos of origin and are cashed in. This is done by the chip monk.
