Your coins look like zinc and the bigger one is probably 5 Pfennig. Most war time coins were zinc and small denominations.
The last of the 5 Reichsmark coins were minted 1939 with a diameter of 29mm and a weight of 14gr. 90% Silver. There are no war time 5 Reichsmark.

Thanks so much for all that information. Looking forward to my next hunt later today. I'm lucky to go out a hour at a time since I have a little one but boy the hunts are fantastic. Can't wait to go out for the whole day.
