That's not the date it was made its when they started making the coins there are suppose to be numbers on the star on the back that tells its worth or when it was actually made
ok I figured it out it's the number in the star itself for the year it was made. look at the star left of the eagle with a 10 power magnifying glass. the year will be inside the star.
I can not tell from your 1st pic what year it is. can you take a even closer pic of the star itself ?
I've tryed a bunch off magnifyi glasses I'm not see number I was thing it might be an error or worn but its not a ruff lookin coin
here's a Ebay close up of a "73 in the star intself. look left of the left wing of the eagle. from your last pic I still cannot make out the 2 numbers inside the star. it might just have been smashed down by so much circulation. put your mouse cursor over the star and now click on top of the star once and it will enlarge to show you what the "73 year looks like inside the star.
It's a coin from Iran: Iran 10 Rials KM# 1259 issued AH 1371-1376 This one is dated AH 1371 (AD 1992)
after rotating you last pic counterclockwise. your first number looks like a 7 not sure what your second number is ??? '70-'75
damn. I was way off on countries. nice find/research.. its metal is aluminum-bronze. it is the tomb of Ferdousi. grade/ value VF-$1.00 XF-$2.00 UNC-$3.75
