Not sure of your question. When you say "face" are you referring to the Obverse? there is no letter A on that side. The only letter A is on the reverse side (eagle side).
As the others have stated, if it looks like it was stamped into the coin, then it would be a counter stamp.
If you can explain in more detail, perhaps it would be easier.
