                  I was wondering if anyone has seen this in a coin before and if so what would have caused it.  It looks to me  as though the planchet was the cause. See how many columns there seem to be. Sent it out and came back surface smoothed. Doesn't look sooth on the contrary it looks rough. Your thoughts would be great.

I would call it more 'tooled' than 'smoothed' but basically an altered coin.

Agreed.  The coin was clearly messed with by somebody for some unknown reason.  People do weird things to coins sometimes and when their "special" coin loses its novelty value, they put it back out into circulation.  Most strange looking coins you find out in circulation are damaged or altered.  True errors command premiums because you don't find them a lot.

Once again I'd like to thank you guys for your knowledge. There's so much variations of issues good and bad with the hobby. It's good to have expert input to our finds. Thanks again

[Mohawk]

No problem, Kevin.

We're always glad to help out around here.  Better luck next time, though.  There's still good stuff out there to be found if you're persistent.

Does anyone have an explanation for the look of those surfaces? I can't recall ever having seen that before.

Hey Bob,

I've seen some cents with that look before, but I also do not know exactly what caused the coin to have that appearance.  I, too, am hoping that someone may be able to jump in here and give us some thoughts on what may have happened to that cent.

Weak Lamination or plating attempt to make it look like a DD perhaps?

Look at the low right next to the letter T, something is missing. Looks Like the coin chipped. Just my observations.

     I'm taking closer pictures that may help clarify as to what may be going on with this coin .I will take it out of the holder if that would help with better pictures. Thank you for your interest in this coin I too thought it was a very strange piece.

It appears to have been cleaned in an ultrasonic generator, which can leave such ripple patterns.

Ultrasonic by itself wouldn't do it.  Not enough energy in any system I've had my hands on  Some sort of acid would etch the copper and the ultrasonic might set up a standing wave and then it got left for a long time?  I've got an ultrasonic cleaner if we want to test the theory.  I like the look.  It'd be fun to take some culls and make them more interesting.
