The botton one has (obverse) a portrait facing right with the legend IMP. FEDERICUS. The reverse has a type of city view (similar to coinage of Hamburg but not quite the same) with what looks to be the initials IGA on the left and MVM on the right. It is silver, thin, and roughly the same size of a US dime.
I've had these two for years now and every now and again I try to identify them, so far without any luck. I am almost certain that they are German, but I don't have reference books for small denomination coinage of that era from that area. I could be well out though. The only thing I am positive about is that they are not French
Any help would be appreciated.
