They are not brass and not wood. Also not from the Trocadero casino. The pictures are nice though [g].

These were made by Mel and Armin for a Reno chip show several years ago. They are bimetal core chips with molded plastic in several colors. Made by Reliable or its succssor company, I believe. They are souvenirs only, not casino chip, and have value only as curiosities. Would make a nice addition to a display on the brass core controversy even though they are not brass.
