Where is the mint mark on a 1917 pfennig?

On a 1917 pfennig, the mint mark is typically located on the reverse side of the coin, just below the denomination or to the right of the design. Depending on the specific mint, it may be represented by a letter, such as "A" for Berlin, "D" for Munich, "F" for Stuttgart, or "G" for Karlsruhe. If you're examining the coin, look closely in that area to find the mint mark.
