Deb,

If you attend the convention, please visit table 31. It would take me a good 10 minutes to fully discuss crest and seals and inlaid lithos. Plus you have the added advantage of Allan being right there to correct all my inaccuracies.

I'm hoping there will be a book in the future on this subject. Currently, Howdy Herz's book on c&s only show those chips made by USPC for which there is a record. There were many other USPC chips as well as chips by the Burt Company. Hopefully, they we'll address all C&S.
