1972 D Kennedy Bin/Bag damage or Failed die 0

[stracy]

Have this coin in a mint set. The shield on reverse is not fully formed.

I have seen this effect before. I do believe this die had a section break away. In 1972, the uncirculated set coins were simply pulled from production. Now they are at least a separate run of coins. (How else could they have all ATB quarters before they are released?)

That's a nice looking Kennedy at least based on the pics provided.  If I were cutting mint sets it's one I'd set aside to review further outside of the cellophane.  The eagle's head, "IBU" right above it, and the top of the shield below it almost always have a friction rub on them.  I'm not seeing anything in these pics.  Finding a damage free reverse is half the way there to 67+ grading.  I'm not sure the obverse of this coins meets that bar though.
