For what it is worth, I agree - 2 Commons.
Mottled pattern of coats is very distinctively different to that of Greys.
It could be sexual dimorphism, though it could also be age difference.
Without seeing a side on view of the seal body on the left it is hard to tell, but it could even be that this is an older female.
As you'll know we don't get many Commons in Cornwall, but the ones we do get tend to be adults and they can be surprisingly large.
