This is only a portion of the piece and it is compressed due to the size constraints. The item is like a medal with an stationary upper portion with a pin that has a trio of coat of arms or national seals. This center of the Maltese Cross is a replica of a token of the engraver to the embassies of England, Austria, and Prussia which was made between 1842-1845. Here is a website that explains the token and the corporation associated with it.https://www.cgbfr.com/corporations-bouvet-graveur-du-roi-tb-,fjt_268108,a.html Any thoughts about this? Thank you
