I have 2 questions. First question is, what company manufactured the brass core chips found at Harvey's and Harrah's.

Second question deals with the below chip from Park in Las Vegas. I'm assuming the Bud Jones manufactured these chips, but was wondering how they were made. They are similar to the CIC chips made by Bud Jones, but what is the inlay made from and how is it inserted to stay in place.

Thanks so much for any information,
CHRISTOPHER
