Request ID help with Ottoman Coin

I have found the silver one of the coin:


But mine is not silver.  It is brass, bronze copper or some mixture there of.
weight:  14.73g  Ø: ~40.0mm  thickness: 1.13mm




Any and all assistance will be appreciated ...

The percentage of silver in some Ottoman coins is very low, in your case .170 (some even go as low as .100). That means that your coin has only 17% of silver in it, the remaining part being copper. That's why these coins look more like copper than like silver.
But that said - if you examine more closely, you'll find the coin having a slightly lighter color than a 100% copper coin would have - there's the silver!

Silver with fineness < .500 is frequently referred to as billon. Probably to avoid this kind of confusion.

Thank you, didn't notice the silver content was that low.  At that percentage, why would they even call it a silver issue… ??  

You can't find many ottoman coins that are not holed.
