We got enough data to assume this coin is way less common than the others : about 90 numista members want to exchange the "1917 A" minted at "87,315,000".
We would expect something similar for the year 1922 A (more or less 60%), however nobody wants to exchange it.
We can jump to the same conclusion by looking for this coin online : I did a quick search but I couldn't find any pictures of it.
For me something happened to the production ; I assume there is a link with the hyperinflation of the Mark and the Occupation of the Ruhr in January 1923 by France (It probably caused a shortage of iron in Germany).
The Mark was almost worthless at this period. I guess the face value of those coins was probably lower than their melting value at the end of the year 1923.
Regarding this context, I guess the Berlin mint anticipated the situation and sacrified its production of 5 pfennig before it was released into circulation.
