Looks more like an open cut rather than a cold shut! :D

Very impressive.

Well and truly, a top buy alright :ok: It would feel pretty thin in the cold shut wouldn't it, must be paper thin, so don't put ya finger thru it :)

I will be a contrarian here and say that's not a cold shut.  It's struck through oil.  The texture of the incuse area is unlike any cold shut I've ever seen and very similar to oil strike throughs.  I think this is confirmed by all the other little oily strike throughs all over it.  Awesome error either way :)

On a learning curve (novice material) here, Mark, but how does a strike through oil result in such a significant divot in the metal as opposed to the appearance of a very light/flat strike (which, so far, I am more used to seeing for a strike through oil)?

If the blob is big enough and the grease non viscous enough (and liquids are incompressible) then sure, I don't see why not.

Very nice! :yahoo:

I'd be interested to know the thickness (of what's left) of the coin in the middle of the defect.

mm, thanks Mark, I would have thought it was a cold shut

OK, it's .65 of a millimetre deep at it's deepest point & thats right near the rim.
When i first looked at it i thought the rough texture looked like struck through grease/oil but i have never seen grease/oil fill with jagged edges like this has ,so discounted grease/oil fill.
Oh & scales battery is flat so will have to get the weight tomorrow.
