The weight is correct for missing one clad layer. (1.8-1.9) It shouldn't look rusty though. Perhaps some better photos of the reverse.
The edge looks about right but I'm not an expert. I thought about taking a picture of the edge but I'm not sure if my cheap phone can do it.
I'll try to get more pictures tomorrow in better light. I wasn't overly satisfied with these, especially the Obverse. My phone doesn't take great pictures. Or maybe it's the operator. LOL
