What I know about Dikeman is from William Erik Voss' ”Silversmiths and related Craftsmen” on the web.
Aaron Dikeman, born 3 Jan 1796 in Norwalk, CT, and died 1882 in Grand Rapids, MI.
He apprenticed in 1811 to David Smith in Lansingburgh, NY, and worked from 1824 to 1837 as a silversmith and jeweler in New York, NY and from circa 1837 to 1867 as a silversmith and jeweler in Grand Rapids, MI. He was listed in the 1863 Michigan State Gazetteer and Business Directory.
If this was a German spoon with the full name A. Dikeman and the initials K&C, I would be rather sure about that it was made by K&C and retailed by the jeweler/retailer A. Dikeman. But now when it is American coin, I do not know. I have searched for K&C, but I am not able to find it. I hope you have the answer and I am most thankful for your help.
Best regards/MBJ
