Here are four coins I've found in rolls recently that I didn't quite know what to make of. I apologize for the quality of the pictures - I am stuck with holding a loupe up to my cameraphone for the time being. The first is a 2006 penny. I *think* it's an internal die break, where the piece that broke off remained stuck to the die, or was partially attached, and created a combination of a die break and a struck through error. I don't think it's PMD because a gouge this deep would expose zinc, there's no bend or dent, and there's no other signs of damage to the coin.   The next is a 1970D penny, that's a little off center and has a weird depression in the rim. The surface inside the depression is glossy. It looks almost like an anti-cud. Is this some kind of clip?  This is a 2011P Native American dollar that came from a mint roll. There is a weird mark below the eye that isn't the right shape for a bag mark. Is it some sort of doubling of the eye? Notice how its shape mirrors the iris and pupil.   This last one I'm a little more skeptical of - it is probably PMD, but I thought I should check. There's a weird groove inside the rim which seems like it might be from some kind of damaged or defective planchet.  |

The first one looks like a good old die chip - that's a popular point for them.
The '70-D is a misaligned die IF the reverse is normal. Otherwise, if the reverse is off just like the obverse, then it is off center. I believe the "indent" is post-mint, but wait for other opinions.
Sacagawea has a sty. (I really don't know about that one).
Not sure about the dime either.

For the chip, does the fact that the piece of die hung on there and was struck through make it more interesting to error collectors?
The '70-D reverse is very slightly off center in the same direction. I guess it's misaligned and off-center, but 90% just misaligned. What would cause a weird shiny depression like that? There aren't any big scratches or warping or a dent that would be associated with getting smashed, and there aren't any kind of grinding marks. There's not any weird discoloration that would be associated with heat or chemical damage.

The Memorial cent reverse seems to have a pinpoint die dent. The 1970-D cent shows a misaligned die in conjunction with an indent. I'm not sure what ails the Sac dollar. The 1999-P dime shows damage to the edge of the field portion of the die. Error coin writer and researcher.

Oh sweet. I haven't seen one of those before. Guess it's a nice keeper!
For the dollar, I have a few more rolls I got at the same time. Should I crack a few of them open to see if I have more with the same defect?
I was reading somewhere about a kind of doubling that was only seen recently on dollar coins, where apparently after striking, the coin smacks into one of the dies while being ejected and picks up some displaced details. Anyone know anything about that and is that a possibility here?

I found the article. Maybe I have an example of ejection impact doubling? Edit: I feel like a heel! The guy who wrote the article already responded. :) Edited by CaptainFwiffo

The indent does not seem to match the curvature of another cent planchet.

I think the striking process would deform the indent some, the same way clips can be deformed a little bit. Looking for other pictures of indent errors, it seems most of them are distorted.
