Description: | Flat, circular disc of copper alloy somewhat resembling a coin-blank, covered on one side by a thick layer of silver/tin coloured material. This white metal could be a droplet of speculum metal, which is the high-tin bronze that is used to make Roman mirrors. This is more likely than a tin coating which wouldn't normally be this thick, or silver metal, which normally corrodes to look either dark brown and waxy, or pale lilac and powdery and/or vitrified ceramic mixed with fuel.
