2006 Caved Nose Lincoln Cent ?

Most likely a "struck through" error... something (grease, dirt etc) caked onto the die in that region, causing a part of the coin to not be fully struck. This usually affects lettering or dates, but can in theory happen anywhere on the coin. Nice find and good eye!

to CCF. Maybe a caved in gas bubble?

Or would it be something filling in the die preventing the nose from getting fully formed? I think it's that, right?

Mrjason,

That was a collapsed plating bubble indeed! Because of the thin copper plating, when the coin is struck, the plating stretches minutely. If any gasses or material was trapped inside during planchet stock manufacture, then chemical reactions occur making those bubbles/lines. Because the nose is a high point, when stacked in rolls, pushes the corrosion/gas around.

I'm not convinced on plating issues yet. Struck through debris or PSD seems likely as well. The current images are not sufficient to call either or. Gets too grainy when enlarged.

I believe plating bubbles and zinc rot occur sometime after strike. This specimen has had eleven years to percolate. If the collapse was due to zinc rot or void in the planchet, I don't see it showing.

Clear close up of the obverse area and whole reverse may shed more light. Thanks, Doug.

Thought I'd follow-up the obverse side of coin shows a nice luster (with a few spots) and shows little circulation for it's age. Finger prints can easily transfer onto the field. Might handle by the edge when possible. Thanks, Doug.

Halo1st: You just may be right about a strike thru, altho I doubt seriously if it is grease, looks more like a chunk of loose metal was imbedded in die if that be the case. I do see evidence of "bubbling" (red circles) and I'm not sure what I'm pointing to...Cheek looks more raised than normal such as displacement. What I'd like to see is a closeup high res of the shape in the nose...is it sharp edged at bottom...is it level of field...any sign of split plating? Lot of questions, my jury's still out!

Also, as to plating issues...read somewhere that in the manufacture of the plating of planchets, that to dry off (Quicker)after the wash, they use compressed air. Just like our computer dusters, just where do you think that "dust" and metal splinters, chips, dirt will land? think that's why so much disparity between coins each year. 1993 & 1998 for example, seem to be a lot in circ in excellent shape, look at the poor quality of shield cents and the 1986-89 years.

Pending the camera, check for macro option or sometimes indicated with a flower symbol. Thanks, Doug.
