<p>[QUOTE=&quot;Loong Siew, post: 3136441, member: 75799&quot;]Hi [USER=84744]@Severus Alexander[/USER] . nice collection.. silver vs AE patination&nbsp; is different. Silver is silver oxide which is darker grey or even black. This coin has that type of patina. I have seen plater ones but Chinese tech back then do not use electricity so they can’t plate it like how we know but rather coat it in precious metal. These often shows signs of peeling off and the oxidation below the coat is pretty obvious.[/QUOTE]</p><p><br /></p>
