Looking through a 2019 us mint explore and discovery set found this lovely red ring toning. Hopefully pictures will be ok. Have any of you got a little treasure hiding?

It does seem that the zinc Lincolns tend to tone very quickly.

I believe the plating is 100% copper vs the old 95% alloy.  Maybe that might make a difference

The toning nice but there is a big gash in the side of his head behind the ear? That may take away some of the pristine of the coin. Maybe it is a scratch in the coin holder

That has always been my theory.
