I believe this is a 50 rials circulating commemorative coin from Iran (KM# 1237.1a,
https://en.numista.com/catalogue/pieces12224.html). The year is 1368 (١۳۶۸ in Persian numerals), according to the Solar Hijri calendar used in Iran and Afghanistan. This is roughly equivalent to the year 1989 in our Gregorian calendar.
I don't think this is really the right section to ask for a coin identification though. That would probably be the
Coin identifications and valuations section.
