Hi Mike. Yes they are both coded. The Inlaid Cloverleaf Chain is PW-BR and it was coded after Dale's book. The Dragon is PA-KH and it is the more common of the two embossed Dragons that are in Dale Seymour's revised edition Antique Gambling Chips. You can now view the links to our Antique Chip Project on Mick Cuddy's web site antiquepokerhips.com here-->
http://www.antiquepokerchips.com/ --> then click on the link at the bottom left in red to view our chip project that Mick has named, "Illustrated Guide to Seymour Coded Chips." This will give you everything including All New Codes through our coded session at the convention.
If you find an old chip that is not shown or you have a chip that is not illustrated with a scan of the actual chip, please let us know.
