Total Eclipse of the Sun - or - Hunka Hunka Burnin' Love on a 2.1

Over the years, I have championed certain slab generations for their educational or historical perspective. Due to scarcity, there are some instances where it is possible to assign a collector's premium to certain generations. Of course, there is also that thought that some generations have been graded on a different scale, and an astute numismatist may see another ratio of value . . . that of a 'crack out'.
The photo below is set to highlight the problem area on the coin. Lets just agree that if the sun has that large a piece of detritus on it for real, we have more to fear that Zombies or a virus. The slab has historical value . . . but will not be the optimal choice for the 'crack-out' artiste. Anyone opening this 2.1 for an upgrade will unleash a corona (get it, a cute astronomical reference ???) that the world has never seen.
Here is one that will stay in the collection as a memorial to our rather challenging time as of now . . . .

Sort of looks like corrosion from that angle. Nowhere near a "total" eclipse, however. BTW, I was in Oregon for the last one, and highly encourage everyone to try and observe the upcoming total eclipse in 2024 in person if possible!
I was scheduled to be in OR for a show during that weekend . . . . the motels and casinos in the area pumped their rates up to $300/night and were booked 3 months in advance. I stayed in SLC . . . . . . .

The garden is still growing in my opinion!
Looks like a major sun spot.....Have you examined it under magnification? If it is inert gunk (is there such a thing?) then should be no problem... if it starts to grow or change color... crack it....Cheers, RickO
