Help With Identifying Coin (Persian )

It's not listed in the Krause world coin catalogue, and it lacks any of the "normal" features found on coinage of the Iranian monarchy (the lion-and-sun, or the Persian crown), so I'd assume it's a medal.

The medal is dated "2536", which is according to the very short-lived Monarchial calendar, dating from the founding of the Persian Empire and only used for a couple of years, just prior to the revolution. Year 2536 equates to 1977 AD.

As for what it commemorates, there are coins issued this same year with a similar design commemorating the 100th anniversary of the birth of the Shah's father, Reza Shah, so it's likely this is a medal commemorating the same event. I assume the portraits are meant to be the Shah with his mother and father.

As for whether it's gold, you'd have to get it tested. A specific gravity test would tell you whether it was solid gold or simply gold-plated.

I can't read Persian (or Arabic). I have a very helpful book, "Arabic Coins and How to Read Them" (which helped with your Zanzibar coin), and I could sit down and try to translate it from first principles, but it'd probably be easier to ask a native speaker.
