Display/Stack Can you identify this unknown coin or whatever it is?

Hi everyone! Ive got this here item and I'm not sure what exactly it is. It looks like it could be an old form of coinage or a coat of arms metal maybe? I don't know for sure but the shape has me stumped And there seems to have been an imprint or some form of image or stamp or markings at one time...I thought maybe a identifying coat of arms or something but it's so weathered I cannot tell for sure. Any help is very much appreciated and welcomed...if anyone knows somebody who might know somebody who might know something about this...I'd be so grateful to you if you think about it next time you see them and could maybe ask and point them to this post please?

It could be something called Plate Money. circa 17th and 18th centuries. Sweden and Russia issued them and possibly others. But I couldn't see any distinguishable markings in the pictures.
