I literally just came across these coins in some old boxes but have no idea if they have value. Can some help.
The 10 pfennig from 1874 stands out to me as from my experience they tend to date to the early 1900's when they turn up so that's a nice early date that you have there. The other two aren't in the best of condition but what is noteworthy with them and the pfennig coin is they are all original and uncleaned. Please keep them that way.
