That is a difference between the first couple of coins (US made for unoccupied or to-be-liberated areas) and those pieces for Germany: The latter were actually minted here - "F" is Stuttgart. The Hamburg mint (J) was destroyed in 1943 and thus did not make any of these. And the others, the 1 Rpf was minted in Stuttgart/F and Karlsruhe/G only, the 5 Rpf in Berlin/A, Munich/D and Muldenhütten/E, and the 10 Rpf coins came from A/E/F/G.
Sometimes I do post images.
But especially when it comes to coins in my own collection, getting them out and taking (good) photos is quite time consuming. So when I need to decide whether I should not reply at all, or post a "text only" reply, I tend to pick the second option. A bird in the hand ...
