Actually, the pictures here on Numista already show the difference!!
have a look at the stars on reverse
they are plain in km#350
and decorated in km#444
very simple!!
Additionally, according to
http://www.chiefacoins.com/Database/Countries/Zine_ElAbidine_Ben_Ali.htm
"km#350: Bi-metallic; Copper-Nickel in center and
Brass as outer ring.
km#444: Bi-metallic; Copper-Nickel in center and
Brass-Nickel as outer ring"
which I think makes more sense
Also, it states the following about km#444:
"Note: The legends on this coin looks smaller than the KM#350 and the stars on the reverse side are decorated"
It also states that both coins have the same reeding style
Now, can someone confirm if it's true that one is round and the other is 12-sided?
and finally, why is km#350 not marked as commemorative here in Numista?
