From what I saw at the photos on the Numista pages of this type and the other types of Afonso V ceitis, these two dots you are pointing are an uncommon thing. Remember that these hammered coins are not identical to each other.
And there's more, your ceitil is in way better shape than most of the ones I saw out there, here on the catalog photos or at the coin fairs I've went. And look that I own a half dozen of these.
One last thing, what defines in what group the ceitil belong to is the characteristics of the castle. And in yours, the castle is 100% visible.
