try collecting the Paul-son equivalent to the BudJones CIC chip. To my knowledge, there were only two Nevada casinos to use these dollars... El Cortez (1) and Golden Gate (2).

You could broaden this collection to all Paul-son metal centers used in Nevada and still have only about 40.

Or broaden it further still to include all known Paul-son metal center chips and have only about 60. There is a $1 chip from Puerto Rico. The dollars are relatively easy. The keys to the collection are the $500 chips from Las Vegas.

There are also a few varieties of these chips with different date codes on the aluminum centers. I believe all the dates are in the 1970's.
