Antique Heavy Metal Relief Portraits With Attached Metal Frames

These relief portraits are some type of silver colored metal, possibly pewter.  They are very heavy.  Each one from corner to corner is 11 inches and is almost 2 pounds a piece.  The frame part appears to have been painted a gold leaf color and the portrait part appears to have been painted a copper colored paint.  The frame and the portrait is all one piece.  There is an attached ring on the back for hanging on each one.  I bought these from the goodwill website for $12.99 for both of them.  They had them listed as brass but when looking at them, they are not brass.  They came from the goodwill in Lufkin Texas.  The website had them listed as Henry VIII and his wife but in my research this is just not the case.  I need some help identifying these as I haven't been able to find anything else like it at all!!  In my opinion they are really interesting and very ornate with the cherubs around the frame.
