This piece is unsigned, but it's possible that it was engraved by William H. Key or George Soley. It is very similar in appears to the types of medals that these two were producing around this time. That's why I purchased this one, anyways.

This example is AU, with a hole, and the reverse has a dark area of pest on the left.

25mm in diameter.
White metal.
George B. Soley or William H. Key?

Thanks for looking!
