Coin/Token Of Unknown Origin Or Age

Yes I agree with @oriole. This one looks pretty modern. If you use the CCF search function with the keywords IMITATION OTTOMAN ALGERIA you'll see what the older ones look like.

While often called "belly dancer tokens", this is probably not the most common use of these pieces, certainly not in their countries of Origin in western Asia and the Middle East. They are generally used in any situation where once actual coins would have been used for decoration. Brides might wear then in wedding outfits. I have seen them jingling from the tops of the drink dispensers of the ceremonial sherbet-sellers walking around the tourist traps in Istanbul.

These "jewellery imitations" are usually designed to resemble at-first-glance the style of coinage once issued by the Ottoman Empire, back in the 1700s and 1800s. But he writing is usually garbled and unintelligible.
