Hi, please show an enhanched image of the marks. I believe to recognize a three tower mark, points to Denmark, see; https://www.925-1000.com/dm_Assay.html
Moinichen known punch has dots: C.I.M. The second figure is hardly 0 because it differs from the first figure that is 0. Most likely it is 9 (1890). If so, it excludes Moinichen.
Irrelevant, the question here is about the CIM mark without dots and an unclear assaying year! Anyway, it could be Moinichen but the year mark is unclear. If...IF it is 90 it is not Moinichen.
For the records there were to brothers Carl Jacob Sophilius Møinichen (1815-1877) and Jacob Møinichen (1812-1877) Both graduated as goldsmiths 1843. They managed a common workshop in CPH. They used both a similar punch Peter shows but used not C.I.M. or CIM punches. The person in this thread is another later person with the same name but different punch (CIM or C.I.M).
BUT! What is interesting and strange is that something is not in place now. The picture Peter show shows also the guardein's punch i.e CFH that is Christian Fredrik Heise who used it 1904-1932. Looks like the later Møinichen also used the long "MØINICHEN" punch. I have not managed to find anything verifying this "assumption". I'm confused????????? Any ideas, thank you?
Another BUT! In the link Peter sent is no mentioning regarding a later "MØINICHEN" punch ?????
Yes, it has become clear during the discussion when it also became clear that there were several masters involved. Interesting discussion in anyway. Thanks for that.
So just to conclude and make sure this is a genuine silver object.
The marks of this 'spoon' represent:
1. The assay mark for Simon Groth;
2. CIM mark for C.I.Moinichen;
3. Three towers above number "00" which represents the year 1900.
As per discussion above the first figure looks damaged and unlikely to be a "9" representing the year 1890 because of CIM mark for C.I.Moinichen (1893 - 1937).
