Is this a coin?

Just found this one : looks like silver / bullion, weight : almost nothing    , diameter : 19.1mm, thickness : 0.5mm - year : 1223-8


Thanks !

looks like Ottoman empire

I'm really bad with this kind of coins but often I believe is that these are imitations of gold coins and are usually worn by belly dancers or at traditional marriages in those regions. I am not sure though could be a real coin too.

Also have a look under Egypt

I don't have my catalog near me .. but I can say that it's 1223-28 not 1223-8 and it must be Ottoman.

looks a lot like this one : https://en.numista.com/catalogue/pieces36883.html

I have had another look and agree with apuking

Yes, it is an imitation. Lots of them about! Very thin usually.

It is an imitation or jewellery or what.
It is manufactured with the hole in it and a bunch of those shall be sewn together to decorate a woman's headdress or her blouse or is atteched to jewellery,
Google: turkish coin jewellery, you'll find a lot of pictures.
