Help with bronze? CA state seal round.

I had a family member ask me for help with a box of world coins they found in a new home they purchased and this bronze round was included.
I though maybe I could get some insight from the forum. I was thinking it was some sort of die trial or jewelers mold. What say you? Thanks in advance.
Added better size reference.

It can't be a die trial, the text wouldn't be reversed.
I was just about to edit thinking that.
But not sure if it were possibly some part of a die making process for a token etc.
It is also incuse

I'm no expert, but it looks like a seal/stamp for embossing paper, or affixing a foil seal to a document. Part of a larger apparatus.
You would get something like this as a result:
Or this:
Die has to be reversed so the end product comes out straight/readable.
Part of this kind of seal/stamp:
Makes sense. I may have to test this theory with my wife’s embosser. Or maybe a vice

My vote also is that it is part of an embossing process.
My own suspicion is that it would be used to make one half of a set of embossing dies (you need a set to squeeze the paper in between) and that this was the master die for one side. On the finished die (made of metal or also in more modern times, plastic/resin) the blank ring would have contained text. It could have been for an official/state seal, or for notary publics' seals.
This type of embossed seal was once common, and notary publics often had a variety of similar things. With the rise of modern photo copiers (which often do not copy these raised seals very well), the usage of these has markedly declined.
I agree with JBK that there has to be an opposing, reversed seal to get the best outcome. Or at least the opposite side has to have some slight "give" to it, so the seal comes out for the best.
Definitely looks like an embossing seal... reminds me of some token/medal I have seen from California... cannot recall which one...Cheers, RickO
Yes Ca state seal was used in several tokens gold and so called dollars. Even a Glendale coin club Dan Car medal.
