I found this in a thrift store and thought it looked interesting due to it havin 4 sets of hallmarks on the bottom. I can’t find much about it, even after several frustratingly-long search sessions… I’m not even sure what it is! Any help would be greatly appreciated!
Here are some pictures of the ‘dish’ itself. I’m not sure if the 5 inserts are glass or crystal, either.
None of the marks are hallmarks. They are all trade marks of one sort or another; i.e. they have been applied by the manufacturer rather than an independent body dedicated to silver testing. If you have read many of the questions and responses here you will know that electroplate, which is what your dish is composed of, has little commercial value.
