Hi, m8s!
I say that it is strange because it looks like silver, but it has two spots which looks like copper. If it was silver plated, the silver must be worn out on the high places. But it not.
If it is silver coin, so how these two spots looks red like copper? Uneven alloy?
Also I need to identify it.
