Off-hand, I know of no published record or documentation of what you are seeking. The records of TR King remain with the owner and I believe he is very aware of the historical importance (to collectors and perhaps others) of those records.

In the meantime, in order to get the information you are looking for you will have to consult the various Chip Guides that exist, and while they will NOT have a complete record, they will certainly have a lot of information. In looking at TR King as a supplier of chips and other gaming equipment, it would seem that California gaming operations were the biggest consumers of chips, however, the vast majority of those establishements were card rooms and illegal gaming operations, which may or may not fit your definition of "casinos". Additionally, several California Native American casinos used TR King chips, but again, those operations may not meet your definition of a "casino".

For California there are several chips guides in existence, to include an on-line guide of both card rooms, some illegals, fraternal organizations and Native American operations. Referred to as the Richard Edward Staeffler Memorial Guide (link here: http://cashcoinconnection.com/Casino/USA/CA/CA_Index.html ) you can view the many chips associated to hundreds of gaming operations in California and make note of those identifies as TR King small crown and large crown molded chips.

For Nevada, which meets the more conventional definition of "casinos" you will be able to find one (or more) of several chips that will have listings of upwards of just over a thousand TR King made small and large crown chips. Those published guides include The Chip Rack and The Official U. S. Casino Chip Price Guide. There are also several other (older) guides available.

Well, this should provide you with a start, but know also that TR King provided chips (in those mold designs) around the World to fraternal organizations, home poker players and other gaming operations.

Good luck!
