Germany 2 Euro 2011 with different letters [solved]

https://en.numista.com/catalogue/pieces18666.html

When looking at the reverse of the coin in the photograph, it shows a 'D' in the outer ring and just above the church building.
The coin I am holding has a 'D' in the outer ring, but an 'A' above the church building.

Is there an error or is this common?

​The mintmark is above the church building and can be all 5 different letters. The "D" in the outer ring is not a mintmark: that D stands for the issuing country D(eutchland).
