Rather than use the dinar as the dollar like Iraq, Iran used it as the cent. So this 50 Dinar coin is just a 1/2 Rial. At current exchange rates, this coin is worthless. Of course, it was demonetized long ago so it is worthless anyway. It features a radiant lion carrying a sword on the obverse and the denomination on the reverse. This coin takes a huge leap from its would-be face value and is worth $1.00.
Ooooh very official looking. So official, in fact, that it made its way here with me forcefully nudging it along. This coin is from one of the thirty-thousand countries that currently wants to blow us up and has been demonetized since it was minted 44 years ago. It features a starving lion carrying a sword in the hot sun on the obverse and a 1 on the reverse. I got it pretty cheap and it's worth about $1.00 in this condition. Not too shabby!
