Please help me identify, thanks
 

Thanks, its very thin. Thiner than any silverware I have ever come across. It can bend easily. Ill post a picture tomorrow just how thin.

Take a very strong magnet and vigorously run back and forth over it. If it moves with the magnet then it is high silver content, 925 or sterling. If it barely moves then it is plate. Silver like copper are diamagnet making a magnet drag when it is moved across the two metals.

Being so extremely thin, and showing no trace at all of plating being worn off the edges, my bet is on Sterling Silver. Also, the "large format" raised-lettering hallmarking suggest it is an early Rogers product in Sterling.

All of that being said, I am not an expert on antique silver and plated eating utensils.

Thanks guys! Here is a pic of just how thin! And a pic of the broken part which does not seem to show plating, still has some dirt on it tho.

I think that has more to do with Eddy Currents and Lenz's law than diamagnetism. When a magnet moves past a conductive piece of metal it induces an electric current and a current produces another magnetic field in the conductive piece. The two fields interacting is what slows it down I believe.
I could be wrong but this is my understanding of it.

But no matter how this works, won't it work with copper as well like in the video?

Yes, if you used a silver pipe instead of copper the magnet would drag the same way.

Actually it works. I have both plated and solid silver ware. The magnet will barely drag on the silver plated ware but will drag the sterling silver significantly.

Hmm. That's really interesting. I guess maybe I don't have a strong enough magnet or maybe I am just wrong.

You need a neodymium magnet. Here’s a great video showing how this guy checks his silver. Hopefully ShinyShores has a sterling silver piece!
