Good rules for chipping:
1. Keep in mind that chips are only "little Pieces Of Clay."
2. You can not get all of them.
3. New chips are turning up every day because more and more people are hearing about the hobby.
4. Chips are not something people throw away. They stick them in nooks and crannies and forget about them.
5. I believe a large percentage of all chips ever made, exist somewhere.
6. If you pay a big price for a newly discovered chip, without waiting for the smoke to clear, you deserve what you get.
