I'm real interested to see what you find on the raised areas on the bust because I found 3-4 of this same die in an OBW a couple of years ago and wondered if the punch operator set the MM punch on the obv die multiple times trying to get the die in the correct alignment.
The raised anomalies are very similar but not exactly alike.
EDIT: I couldn't resist and dug one out. Yours has many of the same markers including the die gouge/ding near the rim above LIBERTY and the long double die scratch from the N (IN)to the hair below the D of GOD. Reverse markers are similar as well but yours has a few NW-SE die "gouges" around the first dot. One of yours actually touches the dot. And the long die scratch from the L (PLU) through the O (ONE) and almost touching the N (CENT) is on mine also. I was hoping to see remnants on mine of the D (raised of course) if it was hard enough to damage the die.
