Very few chip guides, if any, are based solely on one person's collection.

If you see something that has been omitted, feel free to send a scan to the author of the guides, with as much info as you know. I am a minor-league collector, but I have contributed both to Greg's chip guide as well as the Canadian guide. There is a great deal of satisfaction in sharing with others, and it's neat to see my name listed in teh photo credits as well.

Congratulations to anyone who finds an unlisted chip. I hope you are able to share your find by getting it published in an internet guide.
