What is up with this thing? (VERY large images)

[physics-fan3.14]

Hey everyone, for your viewing and grading pleasure I bring you this piece from Tunisia. I am really more questioning the color on the reverse - what is it from, what caused it, do you like it, etc.? I believe the lines on the obverse are die polish lines, not hairlines.

Any idea of the composition? Bronze alloy?

 

Also, what is the general size compared to a US coin?

Wooden Jefferson,

 

The composition is Aluminum-Bronze and the size is between a quarter and half dollar in diameter.

There exsists a possibility this coin once adorned a Tunisian Bride, here's a actual photo of a couple from Tunisia about to enter into matrimony.

 

Aluminum-Bronze, I have no idea how something of that composition would react to tone as such. Perhaps one side came into contact with a camel?

WoodenJefferson...

 

It is a well known fact that camel sweat causes discoloration of coins within the first 10 minutes of contact....

[physics-fan3.14]

Yes, it is a bit larger than a quarter, and its a bronze alloy. My leading theory is possibly dip residue? But like you, I have no idea how that would react with this composition.

[Just Bob]

The reverse appears to have more wear than the obverse, so I'm going to guess that it was attached to something obverse-out, which caused both the wear and the discoloration.

 

BTW, I like the alternating denticles!

 

 

Can you interpret the writing?
