When did Washington start losing his wig?

So you'll notice the super smooth, super shiny, and super bare spots there in Washington's wig. Somehow STG doesn't seem to fit. Do y'all have any ideas as to what's going on there?

Repolishing of the die to remove clash marks or other flaws can leave bald spots in the shallower parts of the die.

Wow! So not the same as a Strike Through Grease but still not an error? That's crazy that they would polish it down  to nothing like that and still use it. I mean that looks bad even though it so smooth and shiny. It would make a good mirror for a pygmy.

You definitely have a coin from a repaired or repolished die.  The workers at the US Mint probably felt that the die wasn't damaged badly enough to retire it, so they just polished it back up after a clash and put it back on the line.  While the US Mint strives to keep errors from occurring ( and strives to keep them from escaping when severe ones do happen), they don't always strive for the highest quality on regular circulation strike production.  The goal for the US Mint in that regard is to make as many coins as are needed to facilitate commerce, and they aren't striving for perfection with circulation coins.  They just want identifiable and presentable.  Your coin qualifies as those things even with George's bald spots.
