This appears to be correct. Just to second this assessment: if you scroll down this article about a small hoard of Mamluk and Armenian coins: http://www.forumancientcoins.com/armeniannumismatics/swat 1.htm, you'll find pictures of two overstruck Armenian Takvorins (no. 15 and 16) that are very similar to @ominus1 's coin (i.e. the same or a comparable overstrike on the same type of coin). The article itself is an interesting read, too.
..a big thanks to everyone who rang in on this esp. those with knowledge and links...and also the comedy..
..as a correction, with help from our good & knowledgeable peeps, this coin looks to be a takvorin of Levon/Leon/Leo lV, king of Armenia(1309-August 28,1341) tribute money paid to and overstruck in Arabic by Al Nasr Muhammed in 1337-38. what a history behind this little piece.
