World CoinsDescription
The
coin commemorates the 8 years of sacred defense, the was against Iraq
1980-1988.
After studying this coin I noticed there was a lot of
chaos about the many variation of dies. I've asked to many Iranian
collector and I received some different answers, with the help of this
and a study of large quantity of coins I had finally the cleanliness.
Also
in Internet and from Krause staff I've found some information but not
complete.
Let's see the differences.
Die Variations.
This coin
have 4 die variations:
- 1 - Obverse with 22 dots - reverse 20 small - rim
sloping to field - Krause 1254,1

dots - reverse 20 big - rim not sloping to field -
Krause 1254,2
- 3 - Obverse with 20 dots - reverse 20 big -
Krause
1254,3
- 4 - Obverse with 20 dots - reverse
20 small
-

So there are 2 variation ether in 20 dot coin and 22 dot coin,
this have probably done some misinterpretation.

In
the following image a difference between two coin have been marked
In 1254.1,
that have less relief, the character 2 have a strong hollow in the
arrow point (see image) in this point the character slope to field,
this does not happen in 1254.2, touching the coin it is possible
to see the difference in relief (for UNC coins the difference it is
more remarkable), the image it is the same you can find above, you can
open that one to see this difference better.
In this image you can see the difference between the 20 characters
The
black line is 1254.2 the red line is the more common 1254.1
On
Obverse only the 20 value have this difference, all other parts of the
coin are equal
There
are not difference in thickness between the two coins. The 1254.1
have a variable weight of 4,53g and 4,57g,
rarely it is possible to find higher weights, the 1254.2 instead have a
variable weight from 4,58g and 4,62g so it is generally heavier.
Attention,
somethimes it is possible to find coins 1254.1 with rim similar to a
flat rim, with absentee slope, but the are not 1254.2 and the 20
character it is always bigger and with less relief.
Rarity:
the
1254.2 is rare, in
Iran have a higher value, about double of the value.
this is my
personal stat:
over 47 coins 41 were found to be 1254.1 and 5
were 1254.2

Now
the other typology of 20 rials, the one with 20 dots, this is the
image of 1254.3 obverse and reverse.

So
1254.3 - Obverse with 20
dot, character 20 big, the coin have always high relief compared
with the two types analyzed before.
Weight variable
between 4,57g
and 4,65g
this type have also a variation I was able to
find, I've discovered that this coin have a different die with a
smaller 20, in this case it is more difficult to notice the
difference because there is no rim difference.
