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.

Some other planchet errors can be found here. http://www.error-ref.com/part-v-planchet-errors/
Thanks, Doug.

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.
