Possibly, especially looking at the hair. The bottom of the '8' is kinda far for a buffer. Also, there is no sign of it being held in a vise, or vise grips.
I know exactly what you have! @mikediamond Struck Through Die Fill: Grease Mold Doubling Great find and example on your number 8 I want to share this webpage with you - http://www.error-ref.com/grease-mold-doubling/

Big difference. In this Grease Mold Doubling example the number 8 is part of the grease "mold" and has moved onto the field. Then it is struck into the planchet, leaving behind a digit of very low relief. In a retained Dropped element, we are talking about no grease involved but a fragment that has fallen into the field of another blank before strike then struck into the new coin thus "Retained".. I'm trying to explain the way I'm thinking of it.. hope it makes sense.
From what I have gathered today, the grease basically covers the entire coin and hardens due to heat. so all the lines would be where the grease pulls apart as the die releases. There are no circular lines really, just vertical ones slightly leaning to the right.
the image was impregnated in the grease, hardened...then struck this planchet, adhered to the die. It not only looks raised, it is raised.
