At what point would a coin have so much damage/corrosion/wear that you'd no longer consider it to be

Just wondering.

I, personally, would stop looking at the object as a "coin" when I could no longer determine the type by inspection.

How about you?

sounds reasonable to me

I propose a new grade that is lower than PO-01: "Non-Coin-0." It would be reserved for corroded brown disks that might have once been large cents, and other various round metal early-1800's things that were worn smooth and subsequently trampled by horses. Of course, there would need to be a registry set for these things.

Hey mgoodm3. I just PM'd You.

Well, I think you've gone too far, if magnetic sensitive dies, MRI's and Xrays can't identify the date anymore.
It could simply be a old utility power box hole filler at that point.
besides what good is a bunch of old corroded discs if you can't tell what the date is, etc.

the existing term for such unrecognizable pieces of metal is "cull".

When it is no longer accepted as "money".
