Ok yes it is rather disappointing to find out you've bought a fake—it has happened to me and most of us here I'd wager. Moving forward, you may want to purchase your ancients at shops on ma-shops.com or vcoins.com rather than eBay. I'm sure @sap could recommend some local ANZ dealers as well.
Thank you for adding the edge pics. I'm not seeing a parting line, but rather metal removal so the manufacturer seems to have sanded down the edge to obscure the method of manufacture.
