Althought c&s without words, in many cases, are custom orders, I agree that they should be coded. However, if a chip has a moose on one side and says Sitka, AK moose lodge on the reverse then it is not an antique gambling chip. However the cross referencing idea is certainly better then just listing them as antique chips...

Suggestion: Take a look at my home page. I have a link "Print the Collection". What I did was make it possible to print all my chips. The format is such that no space is wasted. Each page shows a couple hundred chips. As I always do, I'll have a copy of all my chips (crest & seals and ivories) printed and with me at the convention.
