Can someone please help me with the date? I have read some old threads that point to the numiswiki page (below) that shows the dates but I can't make heads or tails of the squiggly lines. I think I have chosen the correct squiggles for close up shots? Also, this coin has silvering and shows signs of base metal. I this normal? You can see the base metal mostly at the base of the alter. Coin is 25 mm, 3.87 grams. http://www.forumancientcoins.com/numiswiki/view.asp?key=Sasanian Dates There is more than one set of photos. I couldn't decide which was better; set one or set two and posted both.
