unkown coin [opgelost]

I have this coin can someone help me identify it: 

p.s. on the back there seems to be a bull? or other animal with a crown? above it and writing below in arabic and on the front there is like an upside down heart and the date reads 1233 in arabic which I believe corresponds to the years 1817-1818

<front// back> (sorry for quality being bad of photo and coin)

Hello and welcome to Numista!

You knew the numbers for the year but not the 5 (upside down heart) for the denomination?  I think the year is actually 1334 but the picture is a little to fuzzy to be sure of the last digit.  Anyway, it's Iran 5 Rials (1955?).

N#8763 

thanks
