Odd square piece with emblem

[Hillbilly Prince]

I got this years ago for .99 cents at some flea market.
Weighs five pounds, four inches tall, almost as wide and nearly an inch thick.

Looks like a coat of arms with a knight on it....agree on a printing plate.

I think you are right! Once I knew what to search for I found many which looked like this. Thanks!

 

[Hillbilly Prince]

Yes that is it. Thought it might be used to mark something but never thought of that.

What metal is it made of?
