I recently
inherited a large silver Seleucid tetradrachm coin which, to the best of my knowledge is of Antiochus IV Epiphanes. This coin came from my grandfather who purchased it somewhere in Lebanon probably at least 50 years ago.
I know absolutely nothing about ancient coins so I have a few questions:
- How do I tell if it is genuine or not?
- The high relief appears to be shiny whereas the low relief is dark. This looks to me as though the coin were cleaned - does that hurt the value of these ancient coins?
- I cannot find this exact design anywhere. I can only find find similar ones where the figure on the back is hilting up his arm - on this coin he has his arm down on a scepter. I was looking here for reference:

- If genuine, what is this coin worth?
