Its a lower quality of the coin below. http://www.forumancientcoins.com/catalog/roman-and-greek-coins.asp?vpar=107&zpg=49153 Awesome coin in general.
Actually your coin is the slightly more rare version with snakes coiled at the sides of the head. Many of them are poorly struck and there is a wide variation on the die work with some being rather crude. I'd say yours is nothing to be ashamed of. At lease you have the obverse legend. Mine is missing that as well as the reverse:
so it's a republic denarius... gotcha. the title says gorgon, so i was thinking it was a denomination, like a florin. lol.
Very cool coin stainless, a beautiful type. And Mat the example you linked to has an amazing reverse, the details on the horses and everything is truly amazing, and what a beautiful reverse design to begin with!
