These are my first finds in Germany. A clay marble, old flat button with the loop and a very old coin size of a dime approx...maybe some help on it? But a incredible day to say the least.
I would stay away from any soap/water and just use a toothbrush or toothpick.
Sometimes you are only going to be able to see so much detail, dependent on age/soil conditions. A focused close-up picture could suffice if you don't want to clean it.

Maybe an older pfennig. Have fun in Germany. When my wife and I were there on vacation a few years ago I saw a guy detecting in an old field while we were being transported to Salzburg, Austria in a bus full of tourists. Would have loved to stop and check him out.
I sent the coin to a numeristics experts and it is confirmed that this coin is a 16th century pilgerpfennig from Kleve. My first coin dug in Germany is the oldest so far. Wow!
