Pan Pac Half Dollar Toning Cause

Many Pan Pac half dollars have a similar circular / ring toning pattern on the faces around the edges, a circle on the obverse and reverse that goes through the letters. On some, the circular toning is bluish on the obverse. I was wondering what caused this look? Was it the original holders?

Perhaps the ring toned ones were removed from the boxes before the toning had progressed too far and later placed in an album? Just speculating.
It's not toning and I've always felt it was die or striking related as you see the inner peripheral line even on AU examples which have been dipped multiple times.

This si something I have also noticed and thought myself. You can overdip these and still see those "devices".

it's probably an anomoly somehow related to the annealing process which resulted in metal fatigue/softness in that particular area of the die(s). it would be interesting to know if this is unique to one die or to all the dies used to strike the coins.
I recall other threads discussing this topic, maybe do a search to see what others have had to say.

To also answer the original question by the OP, “the coins were sold singly in paper envelopes or as part of a group in velvet-lined black leatherette cases.” (ibid pg. 126)
