Hey Gene!

Actually I didn't know that little tidbit... I'm not questioning your information, yet there are several pieces that are interesting to note and makes one think about things:

1) The material in the Riviera is less dense that that in the Golden Nugget $1.00 chip - as shown in the X-Ray below.
2) The metal disk was added to the less dense material chips to "add" weight.
3) The shape of the H&C's are different between the two chips. The Riviera chip (as does the CJ Sample) has DEEP, shiny and concave hats. The Golden Nugget chips are shallow, 'quasi' shiny and flat hats.
4) Bud Jones of CJ was the designer of the H&C mold as well as the Horse Head Left mold.
5) Burt company made inlay's for several different manufacturers - as their records show - albeit that these records may be interpreted as they made the entire chip... Yet how, with so many different "formulas" (i.e. compositions of base material as who get the metal disk and who doesn't), who gets brass flecks and who doesn't, who gets lead powder and who doesn't, etc. Different sizes of chips. Not to mention all the molds used in the 50's and 60's?!?
6) Bud Jones started his own company to manufacture chips (with metal or coin inlays) after splitting up with Christy (and after Pat Sullivan joined CJ)
7) Bud Jones coin inlay chips seem to be a natural progression assuming that he was behind the metal disk in the center of the CJ chips as well as in the manufacturer of these chips...

I know the CJ/Burt Co/Paulson H&C debates will continue for some time... Especially since the manufacturers don't like to tell how they make their product - unlike the US MINT, as most Numismatists know how coins are made, and what the composition is of each coin...

Just a few things for thought...
