Harrahs has done charity "Monte Carlo" nights for several years, benefiting research on a number of diseases. I don't believe any of these were held at a Harrahs casino. One of their charities is in Boston.

Seems that we should document this chip (and several others of different denoms and years) somewhere. Both TCR and TCG are organized by location.

Any ideas? Is it already documented somewhere (other than Worthpoint)?

This is the only one I have, but would be interested in acquiring others.
