I don't think there is anything on the coin...glue or epoxy...looks like the top layer of the coin is missing or peeled back in the area in question...kind of like a LAM...? I have a 22-S that has a similar surface issue...would yours happen to be an "S"? Just wondering if it might be a supplier issue? I'll try and post a pic when I get back in town Tuesday. Nice find and good pics! smat
Very interesting. At first glance, it looked like something on the surface, but .... It looks like the light is coming from about 9:00 and the glare along the edge under the T (LIBERTY) does make it look like the area is incuse (not raised like an adhesive).
There appears to be an incuse area under the chin as well that seems to have the same dull grey toning. I'm wondering if this could be struck through some type of foil or metal.
The area under the chin would have come off long ago to have toned like the rest of the coin. The brighter area would have come off more recently.
Can you provide an image of the reverse please?

If not glue on the surface then Something acidic could have been spilled on the coin and then ate into the surface. The harsh cleaning lines on the coin may have come from someone trying to clean it off.
