How did I guess, we'd be going here?

Cleaning, straightening and cosmetic surface maintainence is NOT the same as... filling a drill hole, replacing an inlay, removing a cencelation, reproducing a chip, re-filling the hot stamp, repairing a crack, changing the color of a metal core, making a chip that never existed, or a number of other things that "alter" the chip.

I contend that a warped chip, is the same chip when it's straight, while anything that changes the chip, means it has been "restored" or repaired or it's an outright reproduction. (aka fraud)

How about oiling a chip, is that beyond cleaning?

There has to be a reasonable line somewhere, or it's going to be that a cleaned chip, is considered changing it.

ps My dentist now uses computer Xrays, which don't involve processing, film or developing. The "film" is re-usable. Maybe there is going to be a way to do this inspection.

I'll remind everyone of my question before. FLouroscope. They had them in shoe stores. The customers were'nt at risk, but the salesmen got a dose every day. Banned and removed back in the 50s.

There should be some sort of small device, well protected, that would examine something like a casino chip, and show the image on a screen.

Maybe next year I'll open an Xray booth at the convention?
