Ike Peg Leg Question? Possible 74 D Major Peg Leg

I don't know much about these. Seems to me they are just polishing on the hub. Really did not research them.
Here is one I shot for Jeffrey Schmittler at the Michigan State Numismatic Society Convention Spring 2011. It's on 1971-S Proof Ike.

According to the IKe Group the Peg Leg is an intentional "design variety" for the 1971-S Ike dollar which is why it is common (according to James Wiles).

Wiles indicates the Peg Leg ODV-006 is found on 1971-S and 1972-S Ikes with no suggestion that they are anything but common. See his rarity ratings, etc., here: http://varietyvista.com/Eisenhower%...0Changes.htm

Since it is common, and can be found on both 40% silver and CuNi for 1971-S and on 1972-S Proof and Unc (here again rated as common), presumably it affects more than one die. So if there is more than one die, it would follow that the "polishing" occurred on the hub.

On the business strikes, I agree, the abrasion is on the die.

I guess I shouldn't have mixed apples with oranges here as the 1971-S & 1972-S Proofs (and 40% silver Uncs for 72-S) have nothing to do with the business strikes. Two different animals.
