Or just naive?
Why would any of our esteemed club members pay a lot of money to David or anyone else to fix chips and then allow him to mark them so anyone could tell?

I can see the auction headline.
RARE former drilled chip.
Large "W" stamped in the mold.
Buy It now $2,500.

There is only one way to fix it.
They are only little pieces of clay and you can't get em all, anyway.
Refuse to buy ANY un-drilled chip that has also been known in drilled condition.
Do your homework before you buy.
Its called a boycott!!

If you just gotta have it:
Get it in writing that the chip has not been fixed.
Drop by your friendly dentist or Doctor and have him xray it. Then sue the sucker that sold it to you. Or at least file a complaint with the Club.

BTW, if you have any drilled chips hang onto them. It won't be long before they are the RARE ones.
