 That is quite interesting! My best guess currently is a pre-strike lamination peel or other planchet defect. The reverse metal was missing before the strike and that caused the corresponding weakness on the obverse. It's an error, but I agree that sharper pics would help to define/condirm it.

Looks to me like a planchet flaw. A low area in the planchet. Looking at the edge photos, you can see how when it went through the upsetting mill, there wasn't enough material to fully form the rim. It also affected the forming on the Obverse.
Nice find and welcome to the CCF

 New images do show its condition a lot better.  That said I'd like to  scratch my head a bit more and ponder what I think I see. Thanks, Doug.

Prior to blanking, I'm thinking something foreign may have been present during the coin stock being rolled to thickness. That or it rolled out super thin at that position. The cavity is not showing signs of a lamination issue pre or post strike to me. Seems to be some Blakesley effect showing opposite the area on the obverse at 12 o'clock. Indicating the lack of material was present during the upset process, which creates the proto rim. Generally Blakesley effect is associated with blanking clips or material shortage. Thought I'd throw that in there.  One other thought I've read about concerns rolling or bonding stock plates together to create the big contiguous roll. The end of one plate gets pressed into the next, which can sometimes separate before, during or after blanking.  Thanks, Doug.

Thanks Doug! I just started reading "Official Price Guide to Mint Errors" by Alan Herbert. I am a proud rookie and I wouldn't want to annoy avid collectors of coin errors/varieties so if by asking what I should call it is a kind of dumb question, I apologize in advance.

Bwinlanc1, being a rookie myself, when it comes to errors and varieties, I know enough to know I do not know everything. I think spruett001's description "planchet defect" or planchet error sums it up unless someone else has more to add. One of the things I was trying to describe may fall under "Rolling Mill Errors: Rolling Indentation", described better in following link. http://www.error-ref.com/rolling-mi...indentation/Quote: Definition: A foreign object is rolled into the coin metal strip and falls out after the strip is rolled to final thickness.
The object can remain embedded in the subsequent blank or planchet but falls out before the planchet arrives at the coinage press. The result is an underweight blank that has a recess on one face. When struck, the coin displays that same recess and also shows weakness in the same area on the opposite face. Some other planchet errors can be found here. http://www.error-ref.com/part-v-planchet-errors/Thanks, Doug.

Quote: so if by asking what I should call it is a kind of dumb question, I apologize in advance. Not a dumb question at all. I think what you have is a legitimate error and well worth saving. Nice find.
